Acrobat is opening on the wrong screen and maximized

It used to open on the correct screen and not maximized and suddenly it's on the wrong screen, maximized, and when I switch to non-maximized, the PDF window title goes way off the screen, so I can't grab it. I figured out the ALT+Space+M to move it with the keyboard and then put it on the correct monitor, but every time I open another PDF, it's again on the wrong side and full screen. I was able to get it to stop changing to be so large that the top is off the screen, but I can't get it to appear on the correct monitor and non-maximized.

My resolution and display settings are perfect as is and were not altered prior to this issue. The correct monitor is on the correct side. This never happened before and suddenly started happening this morning without me changing any settings and now it will not let me set this to the correct side and to NOT appear maximized.
