Missing email (IMAP)

Missing email from IMAP account (seznam.cz). Specific email is not downloaded with eM Client. In Outlook or on Android device there is everything OK and the email is shown. Emails from different addresses received later are synced without any issues. Only one (containing order confirmation) is missing - all folders checked, I can see it on the IMAP server through web interface (inbox), but it is not synced in eM Client.

I had the same problem with Version 7. I went back to Version 6.0.24985.0 and the problem went away.
