I have a product with two colors, red and blue. This gives me two variants: red/blue and blue/red, for both of these variants, I need the same raw materials. So I created a BOM for the product, added the two raw materials in the components list and selected both variants in the column "variants". Unfortunately there are no materials added to the manufacturing order.

If I only select one variant in the relevant column, it is working! Is this expected behavior?
