Narrative:

We had a status message of duct mon fault come up on EICAS on our CRJ700. Maintenance control was called and it was decided to defer the system based on the minimum equipment list (MEL). The MEL stated it could be deferred based on MEL 36-21-06. The MEL was added via pen and ink change with dispatch and maintenance control to the dispatch release. We are now unsure if we put the correct MEL number on the dispatch release. Because of a poorly worded MEL document we could have put the MEL number 36-21-06-1 on the release with the correct wording of 'air leak detection system duct mon' as the description. The (-1) pertains to both a and B loops being inoperative which was not the case. I believe that the MEL document pertaining to the MEL is poorly worded and laid out as such that would make it very confusing to read and comprehend.
