org-persist warning when archiving

[Colin Baxter 😺]

Hello,

Whenever I archive a DONE item via 'C-c C-x C-a' I get the warning:

Warning (emacs): org-element--cache: Unregistered buffer modifications
detected. Resetting.

The archiving is successful, but I keep getting the warning and
therefore wonder if there is some org-persist or cache setting that
needs to be adjusted.

Best wishes,

Colin Baxter.
