Timing function popup menu bug

Hi, sometimes it happens to me that the “timing function popup menu” will not open.
I tried to duplicate the file, save it with another name, create new timeline but nothing: the “timing function popup menu” starts working again only if I create a new document. How can I resolve to avoid redoing my work multiple times?

What version of Mac OS are you running? (For example, 10.13.6)
