Narrative:

I was working ground control when I heard clearance delivery call to aircraft X; whose flight plan was in front of me. I handed it to clearance delivery and listened to their conversation with aircraft X. There was clearly confusion about the cpdlc clearance upload. I listened to clearance delivery explain all details about the TRUKN2 SID with the syrah transition. I asked the clearance delivery person to have aircraft X file an as soon as possible explaining their confusion. The clearance delivery controller told me afterwards the flight was showing direct syrah off of the airport. I have seen this before and we have had multiple pilot deviations due to this exact confusion. Review/standardize cpdlc uploads so they work for the pilots.
