I think I know what the op is talking about and its not an "module order" problem, its a viewing problem.
When you click to another track, then click back to the previous Pro channel, some modules are out of view and need to be scrolled up to find.
Normally its not too much of an issue but when you have 2-3 extra PC modules and your working on the top (1st in the chain) module it becomes a problem.
Good example- Watch every time I go back to the Bass track.
