Lateral Load Cases not generated with notional loads in load combinations?

Hello, 

I have been working in a RAM SS building model for some time and it has been running without any problems. Yesterday, I shifted a grid that has braced frames on it. After that shift, RAM has been omitting my lateral load cases in the "x" direction in load combinations, when considering notional loads in "all combinations in direction of lateral load". I can only get these load cases to run in combinations when not considering notional loads. I do not have any tension-only members in my model. I've tried deleting, re-entering the braces and columns many different ways, but have not been successful. Please help.
