[Closed] Sora Front Mech/shifter question??

Ok, so i've got a Sora front triple set up on my Planet X London Road. When i change gear from the big ring to the middle ring I have to push the lever 2 clicks, you would think that this would put the chain on the granny ring but there is another click left for that. The limits are set correctly and I can change into big and granny fine but the middle ring seems to have 2 positions.

Has anyone had this before and do you know if my shifter is knackered? I've had it for a couple of years, but it's always done it.....
