No idea. INBOX is treated case-insensitively by IMAP protocol.

Create a test server. Make your Dovecot config minimal. Test with another quota backend. Test with local filesystem. See what change breaks the quota calculation. It is somehow related to your current config, since it's not broken for everybody.
