Can't edit in Word

When I compile to Word .docx, I can’t edit the doc in Word. The read-only Properties are ghosted. I’m running Big Sur and Scrivener 3.2.2.

Same system, same problem, with a twist: I can edit the .docx file but my collaborator can’t. I am exporting to rtf now, which he can edit.

I figured out my problem–I wasn’t signed into Word. My apologies for the inconvenience.
