Missing "Linked" column in weldments cut-list properties

Hi.

So I'm using weldments cut list to control multi body parts such as sheet metal with inserts or rivets.

usually, I must go to the cut list properties and un-select the "Linked" check box column and then I can give each cut list item its own description, surface treatment, etc.. and show these properties in the cut list table.

from some reason, I have a part in which the option to un-select the "linked" checkbox is missing sinse the entire column is missing.

BUT, the properties are actuelly linked! i.e they are locked and I can't change them.

any thoughts
