As "niladri30" suggested, if you are worried, send I-140 copy, EAD approval copy and copy of your RFE notice (don't miss this, possibily make that copy on a blue paper like original one) with a cover letter explaning that when you talked to an IIO you are asked to send all the info again so responding with all info and keep postal/tracking receipts.
Most probably they will simply ignore all the info but you don't need to worry about it any more.
Goodluck
