Remove Nested Stash Tab?

I'm having a very difficult time figuring out how to remove a nested stash tab from a folder. I'd like to move it back to the main tab tree.

Any ideas?

Are you in PoE1 or PoE2? (I haven't played the last few PoE2 patches, I'm not sure if they even have folders)

In PoE1, there should be a dropdown on the tab options for which tab folder you want it to be in, and there's a choice that represents "not in a folder". I don't remember what it actually says on it off the top of my head, because it's been ages since I changed my folder layout.

EDIT: The choice is "Uncategorized"

Guess I forgot to mention for PoE2. I've already got a folder with a bunch of tabs nested inside. The only way I could figure how to move tabs outside the folder was to delete the folder.
