Load/Unload StreamLevel does not work

Hello everyone,

I am developing an editor plugin to switch between stream levels and no matter the methods I use (cf. screenshots), nothing happens even if my logs are telling me otherwise. What is strange is that one of the methods I use is the one described in the UE official documentation…

Thanks in advance for your help!
