Weird values while debugging values in Unity - debugging

Question

I found out while debugging floats and stuff in Unity the values are sometimes off. I.e. I have a float called currentSpeed and when the player is moving this is a value and when he is not it is 0. The problem is when debugging this value while walking the following happens; i.e. 1,1,1,1,1,1,0,1,1,1,1,1,1,0,1,1,1. I found out this is happening with multiple values and Vectors. The weird thing is, when my framerate is lower it doesn't happen (i.e. while having the player selected in the inspector the framerate drops from 60 to 48). I'm using Unity 2018.3 and have no clue how to fix this. I hope someone can help me.
Edit (added code):
void Move(Vector2 inputDir, bool running)
{
if (inputDir != Vector2.zero)
{
// When the player is not pushing we can create a moving direction
if (!playerIsPushing)
{
float targetRotation = Mathf.Atan2(inputDir.x, inputDir.y) * Mathf.Rad2Deg + cameraT.eulerAngles.y;
transform.eulerAngles = Vector3.up * Mathf.SmoothDampAngle(transform.eulerAngles.y, targetRotation, ref turnSmoothVelocity, GetModifiedSmoothTime(turnSmoothTime));
}
}
float targetSpeed = ((running) ? runSpeed : movementSpeed) * inputDir.magnitude;
currentSpeed = Mathf.SmoothDamp(currentSpeed, targetSpeed, ref speedSmoothVelocity, GetModifiedSmoothTime(speedSmoothTime));
velocityY += Time.deltaTime * gravity;
Vector3 velocity = transform.forward * currentSpeed + Vector3.up * velocityY;
// Here we cap the players velocity to a maximum speed. In this case the runSpeed. This means the player can never exceed the runSpeed.
if (velocity.x > runSpeed)
{
velocity.x = runSpeed;
}
if (velocity.x < -runSpeed)
{
velocity.x = -runSpeed;
}
if (velocity.z > runSpeed)
{
velocity.z = runSpeed;
}
if (velocity.z < -runSpeed)
{
velocity.z = -runSpeed;
}
controller.Move(velocity * Time.deltaTime);
currentSpeed = new Vector2(controller.velocity.x, controller.velocity.z).magnitude;
// Debugging the players velocity
Debug.Log(currentSpeed);
float animationSpeedPercent = ((running) ? currentSpeed / runSpeed : currentSpeed / movementSpeed * .5f);
Edit 2: I have tested some more and found out my pushforce isn't framerate independant. During pushing an object in my game I see the weird values while debugging i.e. 1,1,1,1,1,0,1,1,1,1,1,1,0,1,1,1,1,1. I'm working with a CharacterController so adding force to a rigidbody is done via script.
void OnControllerColliderHit(ControllerColliderHit hit)
{
Rigidbody body = hit.collider.attachedRigidbody;
if (body == null || body.isKinematic)
return;
if (hit.moveDirection.y < -.3f)
return;
Vector3 pushDirection = new Vector3(hit.moveDirection.x, 0, hit.moveDirection.z);
body.velocity = pushForce * pushDirection;
}
Might this be the issue for the weird values?
