I'm having the same issue with my MPC. Program change is sent just fine through my Midiface 8x8, but is not sent with the MRCC. I do see green activity lights on the MRCC, but the synth doesn't receive anything. I have no filters set up. I also just upgraded to 1.1.025, without any change.
Additional info... From the routing screen I am seeing the PC messages, however if I go to the MIDI monitor page, I don't see any PC messages.
