BCF200 Faders resetting and getting out of sync with mixer

I have configured Ardour 3.5.403 to work with my BCF2000 mixer. I am using Generic Midi mode with the Behringer BCF2000 Mackie Control preset.

All functions seem to be working except that when I move a fader it snaps back to it starting position. The mixer level does change in Ardour so after making a change the physical fader and software fader are out of sync.
