Apparently Maintenance Control by their mistake while doing the Dispatch Release and sending it out Maintenance Control put in both MELS 74-XX-XX-XX ; Only one can be MELed but not both.During the time I was working on the release for this flight I believe there was only one MEL 74-XX-XX-XX then I clicked on the RLSE button again and somehow Maintenance Control put in both MEL for the RH and LH Ignition SYS A. I failed to notice this and the release was sent.
Dispatcher reported aircraft was released with both ignition system A and system B on MEL in error.
