Close Thunderbird
open the mail folder Delete the folder smart mailboxes in the mail folder. Restart Thunderbird.
That will force the recreation of the whole unified folder settings and hopefully cure your issue..

ScreenShot
Does Thunderbird work in TB Safe mode (see Thunderbird Safe Mode)?
I try to run in safe mode (all addons off, all setting reset) - then i have not grouped folders, so i can't tell if that helps.
Only with addons off - problem still remain.
View menu > folder > unified will give the "grouped" folder list.
I know that :) When i turn on "grouped" folder list, then Folder: Received (Odebrane) has this problem. Dissapering messages doesnt appeall in other grouped folder (Trash, Send.. etc) Only Received.
