I somehow got a reference mark on cue 93 that executes on the marked cue 90. Cue 92 is also a marked cue, but it does not seem to reference that one. Channels 41 thru 50 are marked and starting in Q90 they show a color of "Q93." I don't want them marked, but I cannot unmark them. Cue 90 fires Effect 19 on these channels, a step-based effect that randomly puts one of channels 41-50 at FL. Otherwise they are at 0. Cue 91 stops the effect. Cue 92 restarts it and cue 93 stops it. I've tried removing the marks, but they just won't go away. Automark is disabled, though I have turned it on and off while working on this show. I set the LED color in Q90 and do not change it in cues 91 to 93, but for some reason the board thinks Q93 is a move for these channels and they show a color of Q93 in cues 90-92. I've read thru Chapter 13 "Using Mark," but it doesn't seem to behave as described. The only thing I can think of at this point is to delete and reenter these cues, but they're more complex than I would be able to recreate without introducing another problem. Also, I would rather learn the board well enough to resolve this.
