Are you storing locally as type=Maildir?  Dovecot doesn't use the same
filesystem layout as pure Maildir; here are some details:

/dovecot-maildir
  + dovecot-uidlist
  + dovecot-uidvalidity
  + /cur      # INBOX
  + /new      # INBOX's new
  + /tmp      # INBOX's tmp
  + /.Drafts
  |   + dovecot-uidlist
  |   + /cur
  |   + /new
  |   ` /tmp
  ...

I had originally configured as locally with dovecot.  I did:
=====BEGIN LOCAL REPOSITORY=====
type = IMAP
preauthtunnel = /usr/local/libexec/dovecot/imap -o mail_location=maildir:$HOME/Mail/offlineimap-account
======END LOCAL REPOSITORY======

I would back up your metadata= and localfolders= directories (or the
relevant accounts in them, if you have more than one) and start from
scratch.
