Character Controller based 'dash' function moves strangely in one direction, despite values seemingly being correct.

Hello, I'm working on a pretty simple dash function for my character controller. But there's a weird problem.

In the first picture, the yellow arrow represents actual movement while the green one represents what I want and expect it to do. As you can see, it moves diagonally instead of straight. In the second, it moves exactly as I want it to, In a straight line backwards, as represented by the green arrow.

 private void Dash(Vector3 Direction)
     {
         GameObject WarpClone = Instantiate(gameObject);
         WarpClone.transform.position = transform.position;
         Destroy(WarpClone.GetComponent<CharacterMovement>());
         Destroy(WarpClone.GetComponent<CharacterController>());
         Destroy(WarpClone.GetComponent<Animator>());
         foreach (Transform child in WarpClone.GetComponentsInChildren<Transform>())
         {
             Destroy(child.GetComponent<Collider>());
             SkinnedMeshRenderer[] SMRs = WarpClone.GetComponentsInChildren<SkinnedMeshRenderer>();
             MeshRenderer[] MRs = WarpClone.GetComponentsInChildren<MeshRenderer>();
             foreach (SkinnedMeshRenderer SMR in SMRs)
             {
                 SMR.material = warpMaterial;
             }
             foreach (MeshRenderer MR in MRs)
             {
                 MR.material = warpMaterial;
             }
         }
         Destroy(WarpClone, 100f);
         CC.Move(Direction * dashStrength);

Here's the code for actually moving and creating the 'silhouettes'.

 private void DashFuncW()
     {
         if (Time.realtimeSinceStartup - timeOfFirstButton < DoublePressSpan && Input.GetKeyDown(KeyCode.W) && firstButtonPressed)
         {
             Dash(transform.forward);
 
             firstButtonPressed = false;
             timeOfFirstButton = 0f;
         }
         if (Input.GetKeyDown(KeyCode.W))
        {
             timeOfFirstButton = Time.realtimeSinceStartup;
             firstButtonPressed = true;
        }
     }

 private void DashFuncS()
     {
             {
                 if (Time.realtimeSinceStartup - timeOfFirstButton < DoublePressSpan && Input.GetKeyDown(KeyCode.S) && firstButtonPressed)
                 {
                     Dash(-transform.forward);
         
                     firstButtonPressed = false;
                     timeOfFirstButton = 0f;
                 }
                 if (Input.GetKeyDown(KeyCode.S))
                 {
                     timeOfFirstButton = Time.realtimeSinceStartup;
                     firstButtonPressed = true;
                 }
     }

And here's the code to get the double tap input.

I really can't figure out why it behaves like this; since the backwards one works fine but the front one doesn't, even though they use practically the same values. Any help at all would be appreciated.
