I-765 STEM Extension Rejected - Resubmit with new or old documents?

[pjain64]

Hello,

My application for STEM OPT extension was rejected by USCIS because it was postmarked 22nd December and in the amount of $410 (though it was received by USCIS on 23rd December). Now I am confused regarding the resubmission in the following aspects:

1. Should I resend the application in the amount of $410 or $380, since now the postmarked date will be post 23 Dec, but my original case was based on Dec.22.?.

2. USCIS sent the entire packet of my application back to me, with a green sheet and some stamp on the bottom of each document. Should I resend the same documents as is, or make new copies of the supporting documents and I-765 as I-765 has now changed on USCIS website?

I am very confused regarding these two questions. Please advise. I'd be grateful for any help.
