Okay, I Give Up. Using variables/template logic in my CMS Grid breaks grid output.

It probably doesn't like that you are saying "if condition x, then show columns 1 and 2, else show columns 3 & 4". I think you mess stuff up if you only try to show some of them. (And what do you see in the layout editor with something like this?)

Perhaps you'd do better to put the condition around the widget templates themselves?
