>>65198140You have one too many breaks, you currently have 3 regions set up (left, middle, right). Also I would not use breaks in general for it, use ADDCOMM and ADDCOL or ADDROW, I think they work better.
Another one is to turn off prompt padding, from my testing it is not compatible with region prompt and generally mess things up (you can turn it for regular gens if you want).
Sample catbox with some changes I made to the settings but same prompt.
