I was trying to put all of my applications on Ubuntu 19.10 into folders to organize them. Virtualbox had 2 icons (not running) for some reason, I tried to put them into a folder but it only moved one. After moving the other one out of the folder, there is now 3 icons. After repeating one more time, it has now made a 4th icon. Is there any way to fix this? Uninstalling and reinstalling did not fix the issue.
