What property is related with the column 'Description'? Do a double click in header of column to know. If you wanna you can send print screen or the file and this would become easier to us help you.
For future reference , giving us some screenshots so that we can see what you see would be helpful.
Now if you're issue is that you see something like this
but you had expected to see this
then you can solve it in at least two ways.
Either make the BOM from a lower level ASM instead of the one you did or use the 'promote' functionality on your piping ASM
Hope this helps
Have a nice one
