The lever has some overshift capability which you're using by holding it in place. Based on that I suspect that you simply have the cable too long (not enough tension).

Here's an easier way to cinch up the cable. Shift to the outer ring, and stick a pencil or something into the FD mechanism to jam it so it can't move all the way in. Shift the lever back to the inner position (no need to pedal because you don't actually want to shift. Pull all the slack out at the downtube like you're drawing a bowstring. Set the adjuster to the slackest position.

Now open the pinch nut and pull down the slack. You don't have to pull it all out because the FD isn't all the way in (that's the trick). Tighten, move the FD out and free the pencil, and let it move in. Hopefully you weren't Superman and ended up leaving enough slack for the FD to move all the way in, but if not, loosen the pinch nut slightly so that you can gently pull the wire through and add a bit of slack.

Finish by fine tuning with the adjuster.
