Random/Reversed grid in leagues not working

When creating and editing a league on Racenet for F1 23, you can select the way of determining the starting grid when qualifying is disabled. Unfortunately when disabling qualifying, this option does not work. When I choose a different option than realistic and save the changes in Racenet under edit season settings, it immediately changes back to realistic. When I am in the lobby in game, I as the owner can still see the setting I chose, but all other members only see the starting grid as realistic. When starting a race the grid is also in a realistic order and not in a reversed or random order.
