Drag/drop sessions creates phantom links in menu

Version: 5.8.1.1 Beta

Yesterday I had to rearrange about 100 sessions into PROD and TEST categories. After creating new groups, I decided that it would be faster to just drag and drop them into their new groups. I highlighted several at a time and dragged them into either PROD or TEST as needed.

Today, I noticed that in the tray icon menu, when it comes up there are phantom links in some of the groups called either PROD or TEST (these are listed inside the actual PROD or TEST groups as another link that goes nowhere). These phantom links only show up in the tray icon menu, they do not show up in the full RDM window when restored. I cannot remove these phantom links. Any ideas?

Also - possible feature request - when dragging and dropping, it currently does not highlight where your mouse cursor is. Adding that highlight would be quite helpful, as I missed the mark a few times.

Thanks!
