how to fix? my cutlist properties and materials disappears after rebuild in solidworks

I am modeling a piping design. I have inserted an external part. To insert, i chose a the file i needed and checked the solid bodies, planes and cutlist properties. But after i rebuild the model, the cutlist properties disappears as well as the materials i added. Where did i go wrong? (The version of solidworks i am using doesnt support piping features so i had to do it manually)

hi ML, i already found a solution, turns out that the solidworks cannot find the part i inserted. all i have to do is to open the part (source).
thank you
