Guild Wars 2

I have some issues with rebinding my mount abilities.

By default, they are set on V and C, but the tail swipe shows 1 when I am on the raptor, and if I press 1, it does the ability. If I press C (like when to talk to NPCs because that is my interact key, the raptor hops forward instead.) I have to click Interact to dismount and talk.
I tried rebinding the mount abilities to 1 and 2, but then the raptor just does a hop forward when I press either button. I have to have it set to default C and V and press 1 to be able to tailswipe.

Somewhat same issue. I bind mount abilities to Z,1,2 (summon\skill#1\skill#2) and when I use 1 it just jumps. And it keeps jumping whatever key I assign to Ability #1, however when assigned to 1 it executes Ability on Num1, but if I bind it to Num1 it start to jump on that key as well.

Yes, same for me with the num keys. I press 1 on the top row of the keyboard when assigning the ability to 1, but it only works if I press Num1. But regular 1 works fine if I set the abilities to default (which is not set to any number at all)
