It sounds like to me that the wiring in that specific circuit has been tied together at some point and fortunately for the ones who wired it, they did get the same phase. It should be written up for a sparky to troubleshoot it. If one does not want to troubleshoot it, then simply remove one of the breakers and cap the wire. However, again, it should be referred to a sparky and let him find where the wires are tied together and make the circuit right. Overall it is backfeeding from some place and should be repaired.
