Default Master cylinder bleeder valve leaking?

Has anyone experienced a rear caliper bleeder valve leak under pressure? I have a new to me '10 fxdwg and the rear brake pedal seems kinda soft. Ive bled the line twice, and recently noticed what appears to be droplets of fluid around the bleeder valve area. I don't have a cap on the valve, but don't think that would have anything to do with it possibly leaking. Ive attached a pic of area, and this is after a wash and short ride.
Any suggestions would be appreciated. Dealer charges 125 an hour here and would like to avoid that if at all possible.

First off that looks like the caliper not the master cylinder. Secondly I have to ask is the bleeder tight? If it is i'm not sure never had one do that. Take the bleeder out and make sure the caliper is not cracked around where the bleeder goes. If everything looks good then replace the bleeder.

Make sure there is no debris down inside where the bleeder seats.

If you bleed the brakes, what dribbled out may simply be whats over sitting between the actual valve location at the bottom and top of the bolt. Get a cover for it.

Add:

While I've not ridden one, I understand the rear brakes on later Dynas suck.
