No, that's not likely to be it.

What's the output when you select the mailbox? 

This is the kind of things I get:

. select inbox
* 7925 EXISTS
* 0 RECENT
* FLAGS (\Answered \Flagged \Draft \Deleted \Seen hasnoatt hasatt selected medeleted NonJunk receipt-handled KMAILFORWARDED KMAILTODO KMAILWATCHED KMAILIGNORED $FORWARDED $TODO $WATCHED $IGNORED hasnotd hastd Old $NotJunk $Junk Junk $X-ME-Annot-1 $HasAttachment $IsMailingList $X-ME-Annot-2 $HasTD $IsNotification)
* OK [PERMANENTFLAGS (\Answered \Flagged \Draft \Deleted \Seen hasnoatt hasatt selected medeleted NonJunk receipt-handled KMAILFORWARDED KMAILTODO KMAILWATCHED KMAILIGNORED $FORWARDED $TODO $WATCHED $IGNORED hasnotd hastd Old $NotJunk $Junk Junk $X-ME-Annot-1 $HasAttachment $IsMailingList $X-ME-Annot-2 $HasTD $IsNotification \*)] Ok
* OK [UNSEEN 7924] Ok
* OK [UIDVALIDITY 1148523981] Ok

* OK [HIGHESTMODSEQ 295339131819983] Ok
* OK [URLMECH INTERNAL] Ok
* OK [ANNOTATIONS 65536] Ok
. OK [READ-WRITE] Completed

The "FLAGS" and "PERMANENTFLAGS" responses will tell you if the
mailbox has forgotten about the flags, or if they've been cleared
by something.

I expect from Thunderbird you will see things like $Label1, $Label2,
etc.

Another possibility is some bogus client sending STORE FLAGS rather
than STORE +FLAGS when it wants to set something.
