BOM not using names for all parts

Hello,

I am making a BOM for an incredibly large assembly I have made. I am breaking it down into different sub assemblies for the BOM and it seems that it is naming some parts correctly but others not. It replaces the names with XXX-XXX-XX where the names should be. How can I get SW to show the correct name? Attached is a screen shot of the example of the BOM problem and the original assembly.

Thanks
