Groups and sub-groups display broken after upgrade to 4.7.10
I believe you're referring to CRM-19096 and/or CRM-19219, and possibly CRM-19272.

The first two are fixed with CiviCRM 4.7.11, which is officially released on September 7th, 2016.  The third one has a fix available but hasn't been scheduled into a release.

If you can't wait, and you know how to patch your CiviCRM, you can get the fixes from Github; if you don't know how, wait for CiviCRM 4.7.11, it's only a week away!
