I am using the Ares Murphy template, and I noticed that it has many errors, including the one I described. Most likely, it was made under SP Page Builder 4, which does not have the ability, as far as I know, to change the parameters for many devices outside the computer and you have to do it manually. For this reason, the !important function was used for many parameters, which blocks changes in SP Page Builder 3 and 5. Also, you can't make css changes in modue for parameters with the !important function, but have to do it in custom.css. The menu is also badly done because it crashes when zooming, you could just set the canvas menu when zooming. Topic to close.
