Hi, recently I've got myself a Shimano R8000 groupset, but I've got some issue with the front shifting. Sometimes the left shifter is jammed when I tried to change from the small ring to big ring, but most of the time it's doing fine. Later I noticed the reason is that I touched the small lever together when I shift into the large ring, which causes it to jam. But I haven't got any issue with my Sora R3000 & 105 5800 shifters. Is that normal or something is wrong with my shifter?
