Thanks, Frank.
I can see that your FCB1010's button is sending a MIDI program change message as you press the button in, and then sending the same MIDI program change message as you release it:
P320:

Although your MIDI settings are indeed the same for the two virtual controls, presumably the two virtual controls are implemented slightly differently in those Paramount organs (e.g one designated as latching, the other not).
Either way, the MIDI implementation that your FCB1010 is currently sending from that button (MIDI program changes sent twice -- once as the button is pressed in, and then again as it's released) isn't really appropriate. I recommend reconfiguring it (for all of its buttons) to send MIDI note-on/off messages, as Francois suggested, then auto-detecting them again.
Best regards, Martin.
