Hello everyone,
Today i went to indian lawyer. He told me that sometimes USCIS does random mistakes. So, he told me not to worry about anything. He suggested me that I should send my wife's green card front and back page, make the copy of recipts of i130 and i485 and highlight that says ......LPR and if i want i can send visa buliteen for august and a cover letter saying i applied when f2a was current. He also told me the other lawyer where i went, he gave completely wrong information. So, i feel little easy now and i am planing to send all of the documents by next week once i get other documents for another RFE. 

Thank you so much sajha memeber and also the link send by Kailaketa. These things helped me a lot. I hope i wont get any RFE anymore...
