Hmm, was that an update from 9.3.* or earlier? 9.4 came with a new
option org-archive-subtree-save-file-p. With the default value, the
file is saved when archiving from an Org buffer but not the agenda.
Before 9.4 [*], the file was never saved, so you could set
org-archive-subtree-save-file-p to nil to restore the pre-9.4 behavior.
That should sidestep the issue, though I don't know why you're hitting.
I'm guessing you only see it with dropbox files?
[*] Going farther back, the behavior was to always save. That changed
in 9.1.4 63f6e851b (Do not save target buffer after archiving
subtree, 2017-11-25).
