I'm not showing a RT 2491 in the RT picker, even with the NA option activated. (UltraPak, Build 414, no purchased bonus RTs yet.) It's not in the supertracks dialog either (also with NA's activated). Perhaps this is related to the same problem? Or am I missing something?

Other numbers are missing also from the RT picker (sorted by) number column, with NA activated. If all filters are off, and "show NA" is on, shouldn't the number column be without a gap?
