Topic "delete group doesn't work" a message from mud5150

Running 9.2.6.0 x64. Trying to delete a group from the navigation pane by right clicking and selecting delete group or using the keyboard shortcut prompts with &quotdo you really want to delete group 'groupname' (x sessions)&quot and when I hit yes it just deletes whichever sessions is selected on the dashboard but the group remains. If I delete all the sessions in the group then the group will delete.
