Think you have 2 things going on. I printed the user manual and made a binder so I could study. Makes it easy.

First thing you're doing is enabling AT and selecting base map. Fine. Then enabling Datalog. OK- go AT!

Now here's the second part. You may not have exported learned. So, when you get an AT session done, export and save. Then when you want to carry on with AT, start over on new file with clean Datalog screen.

But, once you start Datalog on a file, even if you turn the bike off, and re-enter Datalog, your log screen will still have current data and now you can resume working on your data file.

So I think what your doing is continuously recording data log to same file. You need to export and save your work. Then when you FIRST select a file to AT, you will be back to a clean data log screen.

Really- You need to print a User Manual so you can study and follow along.

If any of this helped, I'd be impressed

 

Here is the directions in the Autotune manual. Good idea to read it, as will answer lots of questions. If once you ride with the new tune after the export and something has changed for the worse, I open the new autotuned file you flashed to the bike from the PV in Win PV and then open in Compare file the previous file you were running on before you started the autotune session. You can open a VE table front or rear and use the delta to see what changes the autotune made. Pay attention to the area that made the unwanted changes and correct them. That is the way you can learn to do your own tuning. It isn't a easy to learn process the first time, but it gets better. There are lots of good videos on the site also.
Exporting A Learned Tune
Version 1.0.15-1184 of the Power Vision analyzes the learned values ensuring you do not exceed the maximum allowed value for any cell in the VE tables (127.5).
To Export a Learned Tune Use the following steps to export learned data from the AutoTUne process to a new tune in the tune manager that can be flashed to the ECM.
1 From the AutoTune Session screen, touch Export Learned.
Note:Step #2 will only apply if your tuning session yields learned data that reaches the
upper limit of the VE table.
2 Touch Scale to allow the Power Vision AutoTune feature to auto scale the necessary
values in your tune to avoid reaching the maximum allowed VE values.
Or
Touch Cap to proceed with the export and understand that some of the required
corrections could not be made to your tune.
Or
Touch Exit to exit the screen without any changes.
3 Touch Continue to apply all learned values to the tune and save it to a Custom Tune slot
4 Touch a slot to save the tune file.
Note:If there is any data in the selected slot, it will be overwritten.
5 Touch Select to continue with the selected slot.
Or
Touch Cancel to abort the process.
6 Touch OK to continue.
A copy of the tune will be saved.
These are full tunes/calibrations, not just the values learned. This is a version of the tune you started with but the VE (and potentially spark tables) will be modified.
It is time to flash the ECM with the new tune you just saved to the tune manager. Once
the new tune has been flashed to the ECM, you can ride the bike to feel the results or
engage in another tuning session to continue to refine your custom tune. If you do not
flash a tune to the ECM, you will still be running on a tune set up by the AutoTune
feature.
7 Exit to the Main Menu and load your custom tune. Refer to To Load a Custom Tune File.
To Load a Custom Tune File
1 Turn the ignition key to the On position.
2 Verify the Run/Off switch is in the Run position. Do not start the engine.
3 Touch Program Vehicle >Load Tune >Custom Tune.
4 Touch the last tune you saved to the Tune Manager. This will be the tune that contains the
AutoTune corrections.
Note:A tune saved in the Tune Manager will never have those values that are set up by
the AutoTune process included within them, only the values that were learned during the
AutoTune process.
5 Touch Select to continue with the selected tune file.
Or
Touch Cancel to abort the process and return to the custom tune screen.
6 Touch Flash to send the file to the ECM.
Noteo not turn off the key while the Power Vision is flashing the ECM. Once the process
is complete, you will be prompted to turn the key off and wait ten seconds.
7 Touch OK.
8 Turn the ignition key off and wait ten seconds.
9 Turn the ignition key back on.
You can ride the bike with the changes from the AutoTune process or you can start a new tuning session to continue to refine your custom tune.

 

Try clicking the MODE button...

There are a bunch of different "ways" to look at that screen. One of them always has numbers, and a couple are blank, and just count "hits"

I use the one that "zooms" and keeps the target centered, and the data field moves behind it.
