2 windows in Inbox

Suddenly my mail db has 2 windows when it opened. One looks old template (version 5) and another one is new template (but no window title).

When I upgraded Notes 6 from 5, it happened. I installed Notes 6 again after deletion of Notes 5. It was fine but it happened again suddenly.

Please advise me.
