'Current filter' display not updating

Not sure why but the “Current filter” always displays “None” despite it driving to the correct filter. And the big ‘button’ that I presume is supposed to be green is greyed out and says “NA”. My filter wheel is a SBIG CFW8 if that’s relevant.

Yes, the CFW8 doesn’t actually report its position. We can tell it where to go but it won’t tell us where it’s at.

Thanks,
