I can't edit, delete or change 1 single product category

Has anyone experienced this? I have a single product category titled "Stickers" and I can't change, delete, edit, or even toggle on or off it's visibility. 

When I go to delete the category, I'm faced with a popup that simply says "Couldn't Update Category. Try Again."  Does anyone know a solution to this? Thanks

I'm having a similar issue. I'm unable to delete/update a category on my page, and receiving the same message you posted. It's still showing 3 products under the category, but there are no products listed in the category (ghost products). Same issue was posted several years ago with no resolution.

I have the exact same issue and seems they have just ignored the issue or cant seem to fix it. Really frustrating.
