Jumping to random spots in a document

I’ve recently had Scrivener jumping from one spot to another. For instance, if I highlight text and click to add a comment, it jumps to another place in the same doc where my selected text is no longer visible. Second example, when I open the project it seems to go to the correct doc, but a random spot within it (no where I left off). Not horrible, but a bit annoying, and i don’t remember it happening before. I’m running Scrivener V1.9.16.0 on Windows 10 V1909.
