I have a large assembly with several sub assemblies. I have have configurations broken down into component types. The drawing I made has a separate top-level assemblies with a separate BOM on each sheet. For this issue, I have a sheet with a configuration displaying only the CO2 system of the product. The configuration has top level as well as sub assembly parts visible. I inserted a BOM which should allow me to balloon out the view. Auto-balloon does not work at all. Also, I will manually balloon out a part and the sub-assembly will number the items the same when they are clearly different items in the BOM. Every part ballooned in this configuration is a 2. (see image)

Is this because there is more then 1 bom in a sheet set or am I missing something?
