Quoted costs and projects

I have two issues with the Quoting and Project modules (in Epicor 9.05.700C):

1. When a part is engineered on a quote any "Additional" costs added in the Worksheet are ommitted from the "Quoted Cost" on a project.

2. When a purchased part is quoted, the cost does not come into the quote and no cost is included in the Quoted cost in the project.

Does anyone know if these things are bugs or, for some reason not apparent to me, by design?
