Knowing the exact model number will tell the most about the extra clicks you seem to feel. So as another said, pull up the hood and look for the exact part number on the body of the shifter.
But on a 2x front there is an extra click for trimming when in the big big.
It's not quite a full throw of the lever. At least on my ST-5800 series it wasn't.
