Montage Zoom focus after reopening...

I master a lot of stems for one client so I load them all in one montage, one montage per song and the alternate versions are stacked horizontal.

I always close the montage with all the stems visible, but sometimes when I reopen the montage later, the display zoom only shows 4 out of the 5 audio clips for example.

It doesn’t always happen but happens enough to be annoying. Is there anything in settings that would cause the zoom/display to change from how it was when I saved and closed it?

Here is a screen shot of how I left the montage and how I want it to open, and how it decides to open sometimes:
