I have recently noticed that there appears to be tool marks on the inside of my kinu. Is this normal? They are by the bottom stabilizing bar.

Another thing to note is that my 2 bars look more like an x and not + . Maybe it was assembled incorrectly? I have never taken the inner burr or the stability bars out.
