After a little research (shimano TSI), I don't think they have been set up properly at all.
The first shift down shifts from the large ring to the small. I can then shift the FD down twice more (without the chain moving). This was I meant by being able to "shifting down past that first shift."
Looking through the help documents, it seems that the larger outer ring has two positions (something about trimming) and the inner one.
I dont think they have set this up correctly. Would you agree?
too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter
Odds are that it's OK but you're just not used to a trimable FD. The extra click is a fine tuning or trim click to keep the cage from rubbing the chain as you use the outer chainring with middle and inner cassette sprockets.
Use the small clicks to trim as you ride on different sections of the cassette, and shift to the inner whenever you're ready. I don't know if you have a trim adjustment on the inner, but it doesn't matter because you usually can't use the inner chainring with the outer sprockets since the chain coming from an outside angle may touch the outer ring on it's way to the inner.
Now as to the feel of the clicks. It's possible (but I'm not seeing the bike) that the cable trim is a bit outboard and bringing the cage hard against the limit screw. This means that there will be higher than usual cable tension on that last click out, giving you a bit of a pop when you back off.
This may be intentional, anticipating a bit of cable stretch in the first few weeks, or to give you a more positive upshift.
All in all it seems that the bike is right, or at least very close to right, so you should get out and ride it. Every bike is slightly different, and every mechanic has slightly different touch. The bike will settle in and you'll get used to it, and it'll feel perfectly fine within a few weeks.
