Infinite Length Problem

Hi,

Sometimes the auto punch red line, project right end point and yellow cycle bar goe to infinite length.
I do know to create a marquee spot to record and that gets the red line back. But don’t know how to get the project right end and cycle bar to get back.
Is there a way to get it to stop doing that? It happens often. I somehow manage to get things back in place but not sure how or why.
Thank you!!
