I am playing around in capture 2020.0.51 Quartett - no console connected. 

I have 18 wash fixtures - in this case Aura XB. They are numbered and patched sequentially.

The issue I have is that one (or more) of the fixtures won't behave properly. They pan, tilt and dim as they should, but colour seems to live in a world of it's own. I have deleted the fixtures, re-inserted them, changed them to another fixture type with no change. Any ideas?

One thing I have noticed is that when I delete the fixtures, the dmx values remain in the universe window. Bug or have I done something wrong?
