Light output ratio

Hi, in Dialux 13, RDLO+RULO should be =100% light output. This is according to CIE 150:2017. But the value RDLO and RULO never add up to 100% when running obstrusive light calculations in Dialux 13. For example I get an RDLO of 81,64% and an RULO of 0,605%. This make me question the RUL value. Is the RUL value correctly calculated?

Am I not understanding what the values actually are, or is there something wrong with the calculation?
