I'm having an issue where I'm building an assembly that uses a bunch of parts, however the total value of the raw material part does not change. Instead Quickbooks is updating the average cost of the the part based on the new quantity. Struggling to figure out why this is happening. See screenshot for details.

Taken at the extreme, if we have 10 items worth $1,000, that's valued at $100 each. When we build 5 assemblies that use that item, it then shows we have 5 items worth $1000, valued at $200 each.

This consistently causes issues with our inventory valuation summary.
