Those are not addresses in the ecm program. They are the 'ITN' (Index Translation Numbers) for each of those settings. They are only there for documentation/reference purposes, mostly as part of the descriptions. If a person wanted to actually change those particular settings, they would use the CT software to edit those settings via the parameter names, and not any kind of addresses. I updated the pic above to show what the fields are.

I also see that you put the vin# back into the program you sent me. According to the vin#, the engine ser# is not the same as the ser# in the program. I wonder why that is. Is this the original engine?.. or is the ser# wrong in the program?.

According to your program, you have engine ser# 79547693, but your vin# reports engine ser# 79546361. - Which one is the correct one according ot the engine data-plate/engine cover?.?.
