Bug with Manage Accounts - Groups

A few releases ago I noticed that under Manage Accounts - Groups section our groups that we put into the system no longer show up.  Individual accounts still show up fine. When we go to the Account list, we can still see all of the groups in the system.  So we know they are still there and the access is still working.   But, we can no longer see them on the Manage Accounts page.

We recently upgraded to Orion Platform 2018.2 HF5, but that didn't resolve the problem. I see that HF6 is now out, but it doesn't appear like this is something that was addressed in it based on the release notes.

Is this a known issue already?  Is there an easy fix for this? Is it included in HF6?
