No information displayed in the mails bar

Everything is clicable&working exept no information dissplaued (only time)  

Have you tried changing the theme to see if it displays correctly?

I tried just now and it seems to has no effect

Is this appearing in your Sent folder also, or is it just in the Inbox?

Only in the Inbox; other folders are fine.
Do you think that creating a rule of re-directing anything from Inbox to separate folder will solve the problem?

I think that’s a rule you shouldn’t need to create.  You might try:

1.  Make sure you are on the latest release (7.1.31849).  You can go to to get it.

  1. delete the account and re-add it.
