Follow up question.

I made a phone call today and I have no idea why is this happening but NVC told me my case falls under F2B when queried. I got the same answer from USCIS as well. Does that mean for some how my case didnt get transferred from F2B to F1?

I am planning to file in I-485 once my PD becomes current but are they going to change my category from F2B to F1 when my case kicks off? Should I hold my i-485 until F1's cut-off date also hits my PD to save the application fee?

Thank you advance for answering my question!
