Front calipers not releasing

I lifted the brake pedal all the way and the rod moves freely within the MC so I dont think the rod is to long. I also opened all of the bleeders and fluid comes out the front calipers nicely. I also was able to press in the rotors/caliper piston to get the rotors to start spinning yet still riding the pads.

The rears nothing really drops out. I am going to open them longer and see if they start to gravity bleed. I have no idea why the rears wouldn't have anything much coming out of them unless the prop valve isnt getting enough pressure to open the rears?
