The Settings section with name 'Blah' in ConfigOverride 'Config' is invalid. Cannot find a section with the same name

Question

I'm trying to add a new config section to our SF app configuration and it is failing:

Register-ServiceFabricApplicationType : The Settings section with name 'Blah' in ConfigOverride 'Config' is invalid. Cannot find a section with the same name.

Nothing fancy, done this many times before but I'm doing something wrong and I don't see.
