BOM Error

I was working on some sheet metal drawings today using PEM products from my toolbox. Usually when I design with these I throw a BOM on the drawing to show which particular PEM. Today my BOM did not match the items in the assembly. When I put balloons on the parts it counted up correctly. For instance, my BOM table only had 3 parts in it and my highest baloon number was 6. I checked to make sure "exclude from BOM" was not checked.

Any ideas?

Thanks
