I have this sometimes when I use another MUA to access my mailboxes.
To fix it, I make Gnus resync itself completely against the IMAP
server, and it works each time; it can take a long time depending of
the groups sizes, but as I maintain them short, it is not much burden.
Here is what I do:

- unsubscribe from all groups causing problems, and save the
  configuration,

- exit Gnus,

- go into where the agent stores its data files for the IMAP server,
  in my case ~/.gnus.d/News/agent/nnimap/unnamed/,

- edit the agent.lib/local file, and remove references (whole lines)
  to the groups causing problems; do the same in the agent.lib/active
  file if necessary (should not be, but I have seen it sometimes),

- remove the agent files corresponding to the groups unsubscribed,
  which are stored in subdirectories of
  ~/.gnus.d/News/agent/nnimap/unnamed/ directory.

- start Gnus,

- subscribe to the groups unsubscribed above, and open them.


Hope this helps,
