Xbox Controller RT Button does not revert to 0 until other input is applied (some times)

Hello, I am trying to use an Xbox 1 controller to control my game via the "Input manager". I have set up the "RT" button on the controller to freeze the Y axis. It seems to work well 50% of the time but if I press the button quickly or if I hold it in, it sticks when I release it (Debug.Log confirms it is reading that the RT button is being held in). I thought that maybe the buttons were sticking so I tried the LT button and got the same thing. If I set it to Axis 5 or Button 1 I do not get the problem. I still don't think that both buttons are sticking because A)The character starts behaving normally once I press/move any other button or joystick B) it's a new controller and those buttons do not stick in the few games I have tried with it .

The attached image shows the settings in the input manager:

And here is my code:

 //Code that does not effect this has been removed for readability 
 private void GetInputs()
     {
         if (PlayerControlsEnabled)
         {
             this.Horizontal = Input.GetAxis("Horizontal");
             this.Vertical = Input.GetAxis("Vertical");
             this.Jump = Input.GetAxis("Jump");
             this.RT = Input.GetAxis("RT");
         }
     }
 
 //Code that does not effect this has been removed for readability 
 //Note rb2d  is a RigidBody2D
  public void MovePlayer()
     {
         
         if (this.Horizontal > 0) //Move Right
         {
             this.transform.eulerAngles = new Vector2(0, 0);//Flip player to face the right
             if(this.rb2d.velocity.magnitude <= this.MaxNormalSpeed)//Don't excede the max speed
                 this.rb2d.AddForce(Vector2.right * this.ForwardForce * Time.deltaTime, ForceMode2D.Impulse);
         }
         if(this.Horizontal < 0) // Move Left
         {
             this.transform.eulerAngles = new Vector2(0, 180);//Flip player to face the left
             if(this.rb2d.velocity.magnitude <= this.MaxNormalSpeed) //Don't excede the max speed
                 this.rb2d.AddForce(-Vector2.right * this.ForwardForce * Time.deltaTime, ForceMode2D.Impulse);
         }
         if (this.Jump > 0) //Jump
             this.rb2d.AddForce(transform.up * JumpForce *Time.deltaTime);
         if(IsFlying)
         {
 
             if (this.Vertical > 0)
                 this.rb2d.AddForce(transform.up * this.FlyingUpwardForce * Time.deltaTime);
 
             if (this.RT < 0) //If Right Trigger is pressed apply air breaks
             {
                 this.rb2d.constraints = RigidbodyConstraints2D.FreezePositionY;
             }
             else //If Right trigger is not pressed remove the air breaks
             {
                 this.rb2d.constraints = RigidbodyConstraints2D.None;
             }
         }
