BUG - Numpad 1&2 bind cause input lag or delay in action

[vaetris]

Hello,
I'm left handed player and I use arrow and numpad to play the game, when I bind "sprint (hold)" on Numpad 1 or Numpad 2, when I press the keys I have to wait at least 2 to 3 second for the sprint to start.

If I bind "sprint (hold)" to all other numpad key, the sprint starts instantly

Can you fix it ?

Thanks,
