NEW MENU STYLE PROBLEM

[HADIJPM]

I have this issue where, when I want to edit a new menu in my mod, it seems like a file needs to be changed, but I don’t know which file it is! Right now, I’m editing a new menu for the Infinity patch for my game, and this problem has occurred! It seems like the style is still stuck on the old style, and nothing has really changed! I’ve searched everywhere (though not thoroughly), but I haven’t found an answer.
