I'm linking the Dual Wield plugin because I will be mentioning it, and it might be part of the issue, if need be, I will make a spreadsheet with all of the plugins I am using.

So, in the dumb little game I'm working on, I'm using a starting class, as ID 6, and after you unlock the rest of the classes, it forces you to change classes to Hero, ID 1, so you can dual wield as the base class, using Ramza's Dual Wield. After you change from 6 to 1, I used the plugin command "RemoveClassAll 6" to try and remove the base class. Except it keeps showing up in the class list. I'm not entirely sure what I'm doing wrong. I even changed the settings in the class change core settings to not have any classes unlocked by default.
This is all in MV by the way.

Can you please post a screenshot of your plugin list and the event where you use the plugin command?

Almost all of them are Yanfly plugins, and I guessed about where to place the rest.

Have you tried disabling all non-Yanfly plugins to see if a compatibility issue exists?

Just now, yes. It still keeps the class I'm trying to remove.
In advance, thank you for taking time to help me.
