How to prevent Scalability settings from overriding DefaultEngine.ini

Development Rendering
1

General question about DefaultEngine.ini Render Settings.
How do you get them to stick?

ie I have the following under [/Script/Engine.RendererSettings]

r.Shadow.MaxResolution=8192
r.Shadow.SpotLightTransitionScale=4096
r.Shadow.CSM.MaxCascades=16
r.Shadow.MaxCSMResolution=8192
r.Shadow.RadiusThreshold=0.01

And I’ve also set my DefaultEngine.ini Properties to read Only.

But when I launch my project the Project Scalability settings always override these commands.
