Overly complex wall surfaces - New warning for me! (X3)

Well this one is a new one. A wall that has too many openings or mulled units. Haven't researched yet, but I wonder why the program can't have a big flashing arrow or something that points to the problem area. I have tried plan check and it doesn't show up. Any ideas how to find the problematic area?

Found the issue without help from chief. It was a second floor wall extending into the first floor space of a modified bi-level. Not an opening problem, or mulled unit. Go figure. Learning new things everyday. Happy Chief-ing! :)
