Trying To Create "New" Category

I’m trying to create an ‘Anniversary’ category for events. eM Client keeps telling me the category exists.
I’ve searched and searched but I see no existing Anniversary category.
I haven’t created this category before.
Am I that old that I just don’t see it?

Hi James, can you maybe make a screenshot of this error, when you receive it?
Also if you go to Tools > Categories, you should see the whole list of categories existing.

What version of eM client are you currently using?

Thank you,
Paul.
