I have several .org file and typically have them all open in Emacs at the same time. Recently, my agenda started showing one of those file names as "???" instead of the actual filename--whereas, all of the other files display correctly by name.
I haven't made any changes to the files since I created them and all management of the tasks within are done through Emacs or beOrg.
The file displaying as "???" is listed in Dropbox and is readable in a text editor. I checked its properties against the other files that are displaying correctly and everything appears to be the same.
Any ideas on what what might be causing this and how to remedy it?
Everything is otherwise working fine--the items from that file are displaying correctly in the Agenda view, it's just the filename that isn't.
I'm using the following stack for managing these files and tasks:
