Yeah, I could find the custom tags, but I couldn't rename one of my custom tags to season because another tag already had it.

I tried to rename a custom tag to Season, but couldn't because the other tag already had an original name of Season. So I had to name mine Seasons for the time being.
Either way the original real Season tag isn't showing up in the tag editor and I was wondering how I could change it or find it.
And I got MB from this website and I'm the only one who uses this laptop so no one else could've created a tag themselves. And I've only used MB for a few days so I wouldn't know how to create a custom tag not using the Custom fields either.
