Need help with odd community naming behaviour - users having trouble joining my communities

I’m new to Lemmy and am pretty confused by a problem I seem to be having; I created a bunch of communities here on lemmy.world, but I’m having a weird issue with the naming of them, and I wonder if you all might be able to help. I tried messaging the admins of Lemmyworld but haven’t gotten a reply.

The communities I created look like completely normal remote communities to me from across the fediverse here from lemmy.pt, but I see that from inside lemmy.world, they have names that include lemmy.world.

For example, this board /c/wine - from my end it looks normal (https://lemmy.pt/c/wine@lemmy.world) but from inside lemmy.world it’s not got a /c/wine URL, instead it’s https://lemmy.world/c/wine@lemmy.world - which apparently breaks /c/wine links from inside lemmy.world.

I created like 10 other communities that are exhibiting the same problem.

It… seems like posts still get back and forth okay, but I’m at a loss to explain how this happened (I didn’t name the communities foo@lemmy.world when I created them), and I’m unsure how big of a problem it is. I don’t seem to be able to rename the URL component nor can I now create communities with the same name without the @lemmy.world part. My ability to do anything with the mod tools seems nonexistent.

It seems to be causing issues for some users however as I keep getting DMs about it.

If you have any suggestions on how to proceed, I’m all ears. Thanks!
