I have checked with A320 fbw and one website, the frequencies are all good.
I will let my notes here and you can check.
Yssy ils
Rw 7- crs 074-ils 109.90 ok
Rw 16L- crs 168 (1 degree error more than website)-ils 110.90
RW 16R- crs same as RW 16L- ils 109.50
RW 25- CRS 254-ILS 109.70
RW 34L-CRS 347 (one more degree than website information)-ILS 110.10
RW 34L-CRS SAME AS 34L- ILS 109.30.
For gs/ils the frequencies are the same as above, for DME/ILS only rws 07,16L, 25 and 34R. So far doesn’t look like we have any big issue here. I haven’t do a flight, so try to see if these freq are like those you have. I think that is a bad radio config or a bug from Simulator.
Hope this help you
