Why is every incoming mail copied to Trash? No, it is not in the rules!

eM Client 2.7.8039.0 update is making a copy of every incoming mail in trash. This did not happen before the update. Apart from the extra copy in trash, the rules appear to be working correctly. My operating system is Windows 7.
I have now re-installed the eM Client and re-installed the latest update and moved back the saved copy of my data directory and still the problem persists.
Every incoming mail is copied to Trash as well as the correct rules mailbox.

Hello, this was an issue in some versions of 2.7 beta. It is now fixed. Please install update with Help -> Check for Updates.
