Narrative:

Descended out of FL370 to FL310. Center advised we were cleared to FL330, not FL310. Center did say, it's not a problem. Captain read back FL330. I said down to FL310 and put it in the altitude window. Descent and level off made to FL310. Was uneventful and did not appear to cause any conflict whatsoever!
