Narrative:

As I was checking into the hotel in XXX; I was called by scheduling and asked to return to the airport to operate flight XXXX from ZZZ to ZZZ1. When I got to the jet and did the walkaround; the #3 aft [flap] canoe had been removed. I told the captain and we looked in the logbook. The logbook had a yellow configuration deviation list (cdl) sticker that said the #3 canoe was loose and it also had a logbook write-up by maintenance that said the #3 canoe had been removed and 'ok' to continue. The captain and I were both confused by the difference in the yellow cdl sticker and the logbook write-up. The captain called maintenance control to ask and they said that it was all proper and good to continue. We flew the ZZZ to ZZZ1 leg uneventfully. When we got to the gate in ZZZ1; we were told by contract maintenance that the airplane should not have been flown and that it was now 'out of service' (OTS). The new captain was on the phone with maintenance control and was told not to fly it. Since we had talked to maintenance control and given the 'okay'; we thought we were correct in flying the aircraft. Incorrectly applied maintenance procedure by maintenance control.
