It sounds like it's working as it's supposed to. When I'm installing a new cable, I thread all of the barrel adjusters on that cable about halfway in before pulling out the slack and tightening the cable anchor bolt. This provides adjustment in both directions, which is the proper way to fine tune shifting performance.
