I'm running latest versions of Adobe apps with no plugins. My project files are all in a Dropbox folder and I mention that because someone else having the problem uses Default Folder X. Both apps perform actions on saved files.
Restarting Acrobat DC solves the issue but it's still annoying and led me here.
I'm able to reproduce it and there is a thread on the Adobe forums with others who can reproduce it as well:
