To unjam it I have to shift back up one or more times before it will shift down. The cable does not look kinged. Bottom bracket lead is clean. I trimmed the hood a bit to allow the thumb paddle to return smoothly.
I have had problems with the return spring on Campy shifters in the past. I hope that this is not a problem on this new shifter.
What do you think?
Thanks.

When you shift up, you are providing the energy, when shifting down it's the spring. Drag in the system could be the culprit. At the risk of committing heresy, get some Jagwire polished cables (a LOT less drag). Also check routing to make sure all the bends are gradual, make sure the little brass grommet is still in the shifter where the cable comes out and make sure all your cable housings are trimmed evenly and smooth.
