I'm having the same problems getting the descriptions over to the BOM. I have noticed that this only happens with tables starting with M or T (MS, TRMS, etc.).
In the attachment BOM1, this is a catalog check from edit component for a motor. Note that no table is displayed. But if I do a lookup, it goes to the correct part.
In the second attachment, I did the same thing for a fuse. That displays correctly in both the catalog check and the BOM.
I didn't have this problem in Acade 08, it showed up in 09.
