After last update of WME 

Yes. This parameters doesn't work for me and some people who I asked. But RussPA answered that this is WME BUG.If yes, you have to check the SVL > Rendering Parameters > SVL Initially Disabled checkbox, save the settings, and then reload.
That seems to work for me.
I don't know how, I'm not scriptwriter. I only asked you :)About the settings, do you mean through WazeWrap or with another method? I've never done it.
