HI, @Huberth.

The manual calculation of your RR is correct, but jamovi also correctly calculates RR.
Because RR in jamovi, corresponds to yours, it is necessary that in the first cell (A) the combination of the cases encoded with 1 for rows (fum_cod) is shown with the cases coded with 1 for columns (BP_cod).
From the ribbon Data-> Setup-> Data Variable:
Retrieve your fum_cod variable, in the Levels list select encoding 1 (second line) and with the up arrow move it over (do the same thing with BP_cod).
It's about your output ...

Cheers,
Maurizio
