Which Groupset?

Ah gotcha, however it does seem to have the same lever movement as the right one, which means while I was getting used to it I could go through 2 or 3 clicks without actually changing chainring

And don't you mean sprocket?

Yeah actually this is one of the best features of Campag - that you can trim the front mech to exactly the right place so there's no chain rub. So it's not that nothing is happening when you're making the clicks, just that it's moving in smaller increments. Once you get used to it's great.
