Post "delete" test failed

I created a post

• on my home server https://lemm.ee/post/1274899
• on this community https://bulletintree.com/post/818905
• and can view it on a subscribed server https://lemmy.world/post/1578281

I deleted the post. It removed it from lemm.ee, but the post remains on the other two sites. Let me make another test.
