Required Field Error

Hello. I noticed an error in the plugin. The scenario is this: I have a required dropdown field asking “how did you hear about us?” and it works great for new users (everything works as it should). However, if a user already has an account and wants to change to a different level, the only fields that show up are the credit card fields (which is good and should be this way). The problem is that the “required” stipulation is still active even on the dropdown field that is not visible. So essentially they cannot checkout because there is no way to input the “required” information because the field is not visible. How can this be corrected?
