Preview Window Often Shrunk When I Open Premiere Pro

Often, but not always, Premiere Pro opens the preview window at a reduced size when I open the program. Screen shots are attached of what I save the workspace as and how it opens.

What I've Tried:

- Updating the software --> made no difference

- Saving the workspace --> keeps happening anyway

- Saving as a new workspace --> still happens

It's annoying that I have to resize that window over and over.
