Two RFE with same contents different response time

We have pending I485 for 5yrs (EB3), and last received RFE with repsonse deadline on April. Today, my lawyer received aother RFE with same content, but issued yesterday and deadline on June. My question is : do we still need response to the Feb. RFE, and then response for the new one again? Or the old one is covered automatically for the new one? thanks for help.
