New Session Groups do not appear in UI

** This was not supposed to end up in 'Feature Requests'  please move **

Session groups created after upgrade to 19.2 do not appear in UI.  Still not resolved in 19.5.

They do appear in SessionGroup.xml and session groups created in prior versions continue to operate as normal.

Attempting to create a group a second time gives an error it already exists. 

Prior to issue I had 12 groups in addition to defaults. 

I have no extensions installed.
