AutoPLANT Piping Reports for Bulk MTO not showing bolt diameter or length

I need to generate a piping report BOM for our purchasing department and while all the other info is present, unfortunately the stud bolt size, diameter and length does not appear.

I find this strange as the stud bolt info is present and clear on all Iso's generated with OPIM.

How do I remedy this situation?

Cheers,

Steve
