mail.app counter not showing

Question

Apple Mail

Faced a problem when adding multiple accounts to a native client on Mac os. Actually there is 1 account. mail.ru entry and 2 gmail. When mail arrives, the mail counter is displayed only for mail.ru and one gmail. And the counter does not work for another gmail, can anyone come across such a problem? Both accounts have the same settings.

A similar situation, only there is only one gmail mail - and the counter does not work for that one (highlighted the void in red) - help me cure it, please.
