Cannot change condo join permission from singleplayer

When I host my condo, no matter which join permission I select, it always switches itself to singleplayer.

Since I was able to publicly host my condo until recently, which leads me to believe that I just got banned from hosting condos. However, there is nothing showing that I have been banned.

here is a video showcasing my problem:

I don’t recall doing anything to cause this and it just happened randomly one day, which further reinforces my belief that I was banned.

This is not a bug.

This account is banned from hosting condos.
