I have noticed any file opened in any way can do it. I notice if it has not happened yet, i can drag it to the other screen and maximize it and it will appear. Otherwise it will appear at a random time.
Steps i have tried.
-Repair
-Uninstall Re-Install
-Uninstall with Revo Uninstalled (clears registry) and Re-install
-Upgrade from 2013 office to 2016 office
-Ran every windows update
-Disabled all addins
Still persists.
