A problem with my Citra servers

I don’t know if I should post this in Citra Support, but I have a problem when I create rooms in Citra.

So I created 4 rooms in Citra since 2 weeks ago, and everything worked fine. But now, depending on how Citra’s doing or anything, I cannot moderate them when I create them again or I just can’t create them. When I change the port, for example, I can create it, but I still can’t moderate it. I’m afraid now of closing the 3 other ones after I got luck being allowed to moderate them. How can I fix this? Thanks.

Edit: I created them opening 4 Citra emulators, one for each room.
