I don't think you need their marriage certificate. But yes, I am pretty sure they want to see both of your parent's name in the BC. Get a new BC. 

My logic of you not needing their marriage certificate is based on the fact that YOU are inviting them and your BC (later) shows them connected to you. If he or she were trying to invite she or he, then their marriage certificate would come into picture. 

I could be wrong though. Good luck!
