Stop in for a cup of coffee

Busy morning!
I have never had to adjust a Dakota shift cable, so i have no idea how to release the clip. That being said, why is it out of adjustment to begin with?
Thats what I was wondering also. It was fine for a bit moving it around and then all of a sudden went out of adjustment P was almost R etc.. From sitting to long and it streched? Thats the direction It had to be adjusted if that makes sense.
