factor k different for thickness

[themole]

hi, small question , I looked in the group but in vain or at least I do not find the answer, I want to create for individual sheet thicknesses of different styles (15/10-20/10 etc) I do it but when I recall the desired thickness the factor k is never what I associated with the thickness but the last created where I am wrong?

Thank you.
