We are trying to build a new MV and we are encountering an error. After we build it in the Layout Editor, we go into Head Selection and its gray and when you hover over it, it says "WARNING: This layout is incompatible with the frame's active PiP sizes". I've done some searching and can not find any info about this. We are trying to build a simple 3x2 that is left justified, I've attached the picture to show you what we are trying to make happen.
