Weird bug : my community on lemmy.ca is not reachable directly by its short name anymore, I have to ad @lemmy.ca at the end like I would do on another instance

so, I just had created /c/ecriture_libre which was working fine, but now this adress returns a "community not found" error. It is still there, but only reachable if I add @lemmy.ca at the end, like that : https://lemmy.ca/c/ecriture_libre@lemmy.ca

Maybe this happened beacuse I modified the community description with a second mod account from beehaw.org while I was also logged with my lemmy.ca account in the same browser ? And it messed up something... ?

Is there a way to rectify this so the normal addres /c/ecriture_libre can be accessed again ? Is it a bad writing in DB ?

By the way, thanks for your time on here :)
