Some of my existing parts in assemblies are showing the wrong quantity in the BOM.

The quantity column is taking my part's part number prefix (209-002043 for example) and using that prefix as a multiplier for the quantity.  My assembly uses 3) 209-002043 but the BOM quantity column says 627!

I have checked everything I know forwards and backwards and can't fix this!  I've been going around and around with this for hours and I am frustrated beyond belief!!!
