Stash tab dissapeared along with all items inside it

I deleted an empty category, and instead of removing that, it removed another tab next to it with many items inside it. This bug not only removed stash tabs but also messed up my stash completely. I select some categories at all.

Here’s a screen of the issue. As you can see, selecting one tab category somehow selects another instead, and both are highlighted: L3rgmrc.jpg (2855×2680) (imgur.com)

Is there a way to retrieve the lost category and the tabs?

The same just happened to me. I wanted to delete an empty folder, it instead deleted my exalted items folder and its whole content (7/8 stashes).

Any known workaround to retrieve those stashes ?

The same thing happend to me. Lost several tabs with items.
