Configurator X Rules: How to print Price Addition (Not Rolled Up) on Invoice Print R42565?

Hello,

I've configured x rules that generate price additions in separate split positions under the parent item position, e.g. Z1 and Z4.

The parent item is sold for 25,00 EUR plus two additions with 1,00 EUR and 2,50 EUR.

These are the X rules:
Price Rollup is 0, so there are separate positions.

On invoice print, these split positions are missing and thus do not count to the total invoice sum.

Is there a way to print these positions?
After checking the R42565 code, the column SO03 in F4211 has to be 1 or 2 which is understandable with the item help.
(Processing Option "7. Print Kit Component Lines" has to be 1, too, which is the case.)
