Groups gone? Search function removed?

I saw someone posted about groups missing from their page that they are still a member of. Mine has been fine until about a week or so ago and I noticed like 1/3 to 1/2 my groups are missing from my list.
Any ideas what happened?

Also at the same time I noticed that the "search function" is missing on the groups too. Did that get taken or is it something going on at the same time as my missing groups?

Hope someone can help with this!
Thanks!
