Ik on scaled bones get an offset

I am working on a character of which the bones can be scaled.
For the feet i am using the built in IK System, where i get the targets by a raycast.
(this all works fine, the ik targets are being set, and the capsule colliders position
is offset, based on the size of the legs).
The problem i am facing now, is because the legs have been scaled,
the IK position is offset. That means, when i scale the legs to about 80 %,
the Ik target is still put in the right position, but it's bending his legs, as if
the target was higher.
Same happens when i scale them to 120%, only now it's stretching it's legs to below
the ground.
I believe this is a bug, just posting here to see if anyone has come across this before.
code is fairly simple, it has nothing to do with that:

Code (CSharp):

1. if (Physics.Raycast(_currentIkPosition + Vector3.up, Vector3.down, out RaycastHit hit, 10.0f, GeometryDetector.LayerMask))
2.             {
3.                 Debug.DrawLine(hit.point, hit.point + hit.normal, Color.yellow);
4.  
5.                 _Animator.SetIKPosition(avatarIkGoal, hit.point + OffSet);
6.  
7.                 _Animator.SetIKRotation(avatarIkGoal, Quaternion.LookRotation(Vector3.ProjectOnPlane(RootObject.transform.forward, hit.normal), hit.normal));
8.                
9.  
10.             }
