"My Tools" Disappeared

Has anyone had this problem, or know a solution for it? The "My Tools" section of the Tool Chest has disappeared from my screen entirely, and it's not shown as hidden. As a result, I cannot use the numbered hotkeys for tools anymore. I have signed out of my account, restarted my computer, and reinstalled Bluebeam, but nothing has worked. Resetting the settings in preferences makes "My Tools" reappear, but all my preferences were reset as well. So, I restored using a backup, but that made "My Tools" disappear again. I would like not to have to manually restore my old preferences after resetting to the default settings if possible, but I cannot figure out why "My Tools" could have disappeared.
