How to revert back changes in customizations on core doctypes

I was not aware that we can’t customize core doctypes in erp next. I tried to add a field in a doctype called Role and set it to mandatory of which it is a core doctype and cannot be customized. Now the problem is that I think the field I added in in the database because I set it as mandatory and I cannot create any role but when I go to the doctype of the Role I don’t see the field. How do I fix that so that the doctype goes back to its original state
