Renaming a tag

When I first entered the tag: Prophets and Revelation, I misspelled a word. When I go to edit and correct the spelling, it created a duplicate tag so now I have two with the same name and only the last one displays when I want to display a tag. However, when I open the notes>tag, I can see and access both tags.
Can I correct the tag category without creating a duplicate?

Where are you going to rename the tag? Are you using Notes > Tags > Edit?

I am in the notes. I open a tag. I want to fix the misspelling. I edit it then a duplicate tag is created so now I have two with the same name, one spelled correctly and one misspelled. In fact, yesterday I added a note under that category and it formed a 3rd tag so now I have 3 titled Priesthood/Revelation. Frustrating!
