Module positions inside mobile template

Hey there,

yesterday I had this issue: https://stackideas.com/forums/module-position-inside-mobile-template I thought it was solved but unfortunately it is not. Could you please assist me since it stopped working for no reason and I can not get it back to work.

Could you please try to copy the module "dating search" and make the new one being shown on mobile only? No matter what I try it is not working again.

I am trying to get a copy of the dating search module getting shown on mobile on the lower left button "Mehr" on my live site under /community/benutzer. Tried for two hours now and it is not working, no matter what I have tried to do...
