Not able to create side room threads


Hello all,

I noticed this now twice that I could not set the topic for the side room on creation of the thread or in edit. I also tested by requesting the desktop site and trying, it does not work either. This is in safari. Is this a permission or is this a bug of the website? Please advise.

Also please move my food thread to the side room, thanks
