Shifting to the smaller ring up front is a harder shift and will make a clank or hard "tack!" noise as it releases cable tension. It happens even with Ultegra shifters and, I suspect, with Dura-Ace. It will not feel like the soft click you get with the rear derailleur shifter. This seemingly unrefined feeling and behavior is normal.
Ardor, that is probably the front derailleur trim function. You can set the front derailleur slightly left or right on your current front chainring so that it reduces noise from the chain rubbing the front derailleur when you go to the extreme high or low cogs of your rear gears and cause excessive cross-chaining. There are two positions for each of the chainrings on your bike.
Moving the shift levers part way will cause the shifter to go to a different trim position. You will feel a slight click and detent partway through the lever sweep, and if you push further, it will go to the next chainring. If you are already in the high trim position and you try to go to a higher chainring, the shifter is smart and will not click to change the trim. It only clicks if you will be changing the detent position from the one you are currently using. The click from going to a lower trim position using the black plastic finger paddle is more noticable than the one you will feel while going to a higher position with the alloy brake levers.
