I have several Groups set up in my Nav pane with the appropriate shortcuts under each group. At least once per week, I open the shortcut pane to find a second set of Groups at the top of the list, no duplicate set of shortcuts. Sometimes, the groups are at the top and the shortcuts are below - in no particular order, just there.

How do I get the shortcuts to stick with the groups and how do I get the groups to stop duplicating? I can't seem to find any KB articles, unless I'm just not using the right search for keywords.
