Scalability Settings Reset When Going Full Screen

On UE 4.21.2 Source Version

Doing a custom scalability settings UI (View Distance, Foliage Quality, Texture Quality, etc.). Everything works fine and saves settings and applies except when I press “Alt-Enter” to go Full Screen. I can change the Scalability settings, they apply, they save even if I restart, but if I hit alt-enter and go full screen, they reset to default no matter what.

Steps to reproduce:

  1. Change sg.x setting (Viewdistance, texturequality, etc.)
  2. press “alt-enter” to go full screen.
  3. settings revert to default

Here’s the blueprint that saves the settings:

Do I need to save a different set of settings to affect full screen? Should I just stop the player from going full screen and just go full res in windows mode? What is the advantage of full screen of window mode a full resolution?

Thanks!
