Character Controller 'Dash' acting weird.

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







As you can see in the first picture, the 'silhouettes' move in a straight line backwards, which is what I want. However, in the second picture, they move diagonally. Which isn't what I want. This is strange to me since the one Forwards uses transform.forward, while the one backwards uses -transform.forward. Therefore I have no Idea why It doesn't work.

Code (CSharp):

1. private void Dash(Vector3 Direction)
2.     {
3.         GameObject WarpClone = Instantiate(gameObject);
4.         WarpClone.transform.position = transform.position;
5.         Destroy(WarpClone.GetComponent<CharacterMovement>());
6.         Destroy(WarpClone.GetComponent<CharacterController>());
7.         Destroy(WarpClone.GetComponent<Animator>());
8.         foreach (Transform child in WarpClone.GetComponentsInChildren<Transform>())
9.         {
10.             Destroy(child.GetComponent<Collider>());
11.             SkinnedMeshRenderer[] SMRs = WarpClone.GetComponentsInChildren<SkinnedMeshRenderer>();
12.             MeshRenderer[] MRs = WarpClone.GetComponentsInChildren<MeshRenderer>();
13.             foreach (SkinnedMeshRenderer SMR in SMRs)
14.             {
15.                 SMR.material = warpMaterial;
16.             }
17.             foreach (MeshRenderer MR in MRs)
18.             {
19.                 MR.material = warpMaterial;
20.             }
21.         }
22.         Destroy(WarpClone, 100f);
23.         CC.Move(Direction * dashStrength);
24.     }

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

Code (CSharp):

1. private void DashFuncW()
2.     {
3.         if (Time.realtimeSinceStartup - timeOfFirstButton < DoublePressSpan && Input.GetKeyDown(KeyCode.W) && firstButtonPressed)
4.         {
5.             Dash(transform.forward);
6.  
7.             firstButtonPressed = false;
8.             timeOfFirstButton = 0f;
9.         }
10.         if (Input.GetKeyDown(KeyCode.W))
11.        {
12.             timeOfFirstButton = Time.realtimeSinceStartup;
13.             firstButtonPressed = true;
14.        }
15.     }
16.     private void DashFuncS()
17.     {
18.         if (Time.realtimeSinceStartup - timeOfFirstButton < DoublePressSpan && Input.GetKeyDown(KeyCode.S) && firstButtonPressed)
19.         {
20.             Dash(-transform.forward);
21.  
22.             firstButtonPressed = false;
23.             timeOfFirstButton = 0f;
24.         }
25.         if (Input.GetKeyDown(KeyCode.S))
26.         {
27.             timeOfFirstButton = Time.realtimeSinceStartup;
28.             firstButtonPressed = true;
29.         }
30.     }

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

I'd appreciate any issues you can see.
Personally, I suspect it has something to do with the Character Controller colliding somehow with the ground, and therefore sliding diagonally.

 

I am thinking only in your forward animation.
