Should I ask the petitioner (my mother) withdraw an approved family petition (approved I-130 F2B, unmarried son, I am already married now) as I have already received my green card through an employment based application.

I just received a form 3032 from NVC even though me and my spouse already have our green cards. A side note, we were expecting the family petition to be withdrawn automatically because of marriage, and then because of the green card approval but the petitioner and I have both received notification from NVC.

What would the best course of action (if at all) be?
