Thx for reply, indeed, on a newly created site the location group appears. It means that I will have to rebuild the site I have from scratch :(((( ... that's not so easy

I use 2 controllers : 1. software linux 5.12.7 and 2. OC200 5.12.9 On OC200 5.12.9 can't find "location group" on gateway acl, even if I have create one location group. <- versus -> On left is 5.12.7...
