Solidworks / EPD 2012 SP4

I have an assembly using multiple configurations from common SLDPRT and SLDASM files. The computed BOM is correct after I check-in the assembly. After it is transitioned from under editing to approved, the computed BOM is not correct. It combines the part configurations for each SLDPRT or SLDASM file; showing the @ configuration in the BOM's configuration column. EPDM's BOM compare shows the change. Toggling off the "As Built" check box fixes the BOM.
