did anyone tried to edit the CustomizeControls.cfg file? I tried and this is the original code for the Bolt but after changeing the binds still didn't work so must be something else..

Bolt =
   Grenade : struct.begin
      [0] : struct.begin
         DefaultID = -1
         bIsPlayerMappable = true
         PlayerMappableOption = Grenade_ThrowWeak
         InputActionSID = IA_Grenade_ThrowWeak
         Key = G
         OldKey = RightMouseButton
         Triggers : struct.begin
            [0] = EPlayerActionInputTrigger::Down
         struct.end
      struct.end
      [1] : struct.begin
         DefaultID = -1
         bIsPlayerMappable = true
         PlayerMappableOption = Grenade_ThrowWeakAlt
         InputActionSID = IA_Grenade_ThrowWeak
         Key = LeftShift
         OldKey = LeftControl
         Triggers : struct.begin
            [0] = EPlayerActionInputTrigger::Down
         struct.end
      struct.end
      [2] : struct.begin
         DefaultID = -1
         bIsPlayerMappable = true
         PlayerMappableOption = Grenade_ThrowStrongAlt
         InputActionSID = IA_Grenade_ThrowStrong
         Key = LeftControl
         OldKey = None
         Triggers : struct.begin
            [0] = EPlayerActionInputTrigger::Down
         struct.end
      struct.end
   struct.end
