"drafts4" tag persists even when no drafts has it

I renamed the “drafts4” tag to “z - drafts4” so that it would sort to the bottom of the list.

I have confirmed that there are no longer any drafts tagged with “drafts4”.

(Note: using Drafts on iPad Pro (12.9-inch) (3rd generation) running iPadOS 15.3.)

Expected: “drafts4” would no longer appear in tag filter list.

Observed: “drafts4” still appears in tag filter list, as does “z - drafts4” (see screenshot).

Have you checked your trash folder too to make sure no drafts in there have it?

They are still ‘in the system’, so the tag would remain in the system until any such drafts are expunged.

That did the trick. Thank you.
