I had the same problem and solved it by reverting this commit:

Hello,
I have some trouble using "doveadm altmove -r".
Regular "doveadm altmove" is OK, selected mails were moved to alternate
storage as expected. But I can't manage to get them back to original
location, "doveadm altmove -r" has no effect.
We are using Dovecot 2.3.4 (Debian Buster package).
mail_location = mdbox:~/mdbox:DIRNAME=_@@_dbox-Mails_@@_:ALT=/slow%h/mdbox
doveadm altmove -u myuser since 90d
-> some message files are created under /slow/my/homedir/mdbox/storage
doveadm altmove -r -u myuser all
-> message files are still sitting under /slow/my/homedir/mdbox/storage,
none were created into /my/homedir/mdbox/storage.
Is there some known issues with doveadm altmove in this version ? Or am
I missing something ?
I can share more config details if needed.
