Unsuccessful at deleting lemmy.world account

I have accounts on Lemmy.world and Blahaj Lemmy and kbin. I would like to delete my account from Lemmy.world as they are not defederating from Meta/Threads. Plus, Lemmy.world is huge and spreading things across the fediverse makes sense.

When I go to Settings and try to delete my account in Lemmy.world, I'm asked to enter my password, I do, the response is a 'Saved' message, but the account is still there.

I want to keep my instance on Blahaj Lemmy, just not my instance on Lemmy.world

There must be an answer that I'm just not seeing. Thoughts?
