I am grouping by Tag in this example.
1. Frequently, the Tag name is randomly missing from the Group (and the Groups are sorted incorrectly):
2. Refreshing usually fixes it (The names come back and with proper sorting), but the names are flickering many times after hitting F5:
3. I am using alternating gray and yellow in my Grid. However, the groups and first items are all gray. See below and top image. Is it supposed to alternate?
