"unknown" folder showing up in SQL Tags Browser

I created a SQL tag and don’t know why, but it didn’t show up. So I refreshed tags and then found a sub-folder named “unknown” with the tag in it. I can move the tag to the correct folder, but I can’t delete the folder. when I try, it asks if I’m sure I want to delete this tag. Now I have a couple of these unknown folders in different sub-folders in my tags database. How can I clean this up?

If you try a refresh or restart the gateway and you should be all set.
