One last check - you are showing Track 1. Do you have any other Tracks defined?
In my LMS sequences, I use Track 1 as a Master Track and ALL channels are present there, but it is possible to put channels in other tracks that aren't in Track 1 and that can cause problems. I actually do most programming in Track 2 or higher because I can move channels around or delete without affecting the most important Track (Track 1).
