Backend editing of keyword different to upload?

This is by design. You should really use meaningful keywords when submitting. when pictures have been accepted, you should only occasionally touch up the keywords or the title, to correct a typing mistake for example. It would be easy, to bypass the checking, if you could bulk change keywords or titles after the pictures went through the aproval process. It did teach me, to be careful with keywording before submitting. And btw, if you use the AI to keyword, you really should delete non-relevant keywords, because with time, irrelevant keywords will hurt your ranking.

Not that I wouldn't love to have a better way to correct mistakes, but at least, I'm grateful for the opportunity to do it.

I suppose it was designed that way because we're meant to fine tune keywords before submitting the image. I do sometimes add or rearrange keywords once they've been approved, but I don't make any drastic changes so having to do them one at a time isn't too time consuming.

This appears to be a contributor related question, moving to contributor forum.
