Unread indications disappeared from sidebar

[stripes]

Hello there.

I use Macs, so Mac Mail, and Virgin Cable, so Virgin email.

All well until recently, when for no good reason, the little circles showing unread messages have disappeared from my Mail sidebar. My partner also has a Mac, and it's the same on her machine (mine is a Mac Mini, hers a MacBook Pro). Both running Yosemite, all latest browers etc.

Tried and tried hunting through preferences for an answer, none came up.

Not the end of the world, of course, but annoying as now you have to click on each mail account to see if you've got any new mail!

Any answers very welcomed.


Thanks.

Allen.
