It worked, but it shows all the modules and that's a problem. I tried to use the codes you mentioned, but none of them work. Only specific modules should appear.

In the second case, I tried to put it in the HOME-40 position, but the position does not exist for choice. It exists in the template, but not in the choice. So I put it on SIDEBAR-2, I put it to appear only in PHONES, but it appears general

To solve the problem temporarily, I had to disable the position on equipment with WIDE, XTABLET, etc.
I need "Responsive utility classes" to work correctly, as we will need to create other specific modules.
