Yanfly Class- Learn, sub and change help

hello I'm trying to get a sorta specific result out of the Yanfly plugins
skilllearning, subclass, and classchange systems

Im trying to make it so that subclasses don't show at all when switching classes
and make it so regular classes don't have the learn skill option in the menu

And what's the problem?

When changing classes like main ones classes deemed as subclasses show up as well
my game has things called artifex that only effect what skills you learn and you them with job points
im using it in place of subclasses so i need to hide them and hide regular classes from the learn skill menu
thank you for your help
