I too faced this issue (I deal with oranges). You can override
mrp_production.action_compute() to fix this. A version is attached. Pass
the raw_product_id and raw_qty in the context.

However, in the end I decided that Manufacturing Orders add far more
complexity than benefits, so now I just create Production Lots directly
with a custom wizard for each type.
