Changing graphic settings in game ignores the default scalability settings/source/ini file?

There are 3 ways of changing a graphics preset: via “Execute Console Command”, via “Set Overall Scalability Settings”, and with “Set Foliage/Shadow/Texture/… Quality”

Apparently whatever you put in your DefaultScalability.ini is completely ignored unless you go with the 3rd option. I’m not sure why the “Set Overall Scalability” node doesn’t take into account project’s .ini file - learned it the hard way
