Okay So I tried this, I set up a quick LRGB test, before I did that I went to the blank filters and put in unused+slot number or sequence number. Then I made the test, and I check the autofocus before start. So the interesting thing here is that focus worked, except it focused prior to every filter run. And L G B worked fine but instead of the R filter it used the unused2 instead. It did get LRGB correct before putting the unused in. here is the log.
