How do we rename or delete an optional ankihub tag?

I am a maintainer of an optional ankihub tag (MWU_CCOM) and I know how to successfully create an optional tag, however, I cannot figure out how to rename the tags and have the previous old tags be deleted after the renaming. On my end, renaming the tags is creating new tags on the cards, but it is also leaving the previous tag on the card. I can manually delete each card’s old tags, but how do I sync the renaming/deletion so new subscribers only have the new tags? I watched the videos but I think I’m missing something.

I included a screenshot of a card that has 4 different optional tags after renaming the optional deck cards, but my goal is to have only one updated (renamed) tag so there is a nice sub-tagged index of the cards.

Thanks so much in advance. What you all are doing at AnkiHub is AMAZING. Much love!
