Help: I-485 RFE/NOID - Ask for I20 - No Gold Sheet

Just got a RFE regarding my I-485 application from USCIS. Very interesting that it asked for I-20 copies. Now the problem it didn't come with a gold sheet. Can anyone who has had this kind of experience share how you responded without a gold sheet?

Any thought will be appreciated.

P.S. my case is EB2/2004 - so you know my case has been and is being screwed up:)
