Loading Screen System (Level Transitions w/ Progress)

I am trying to have my Level Load using the Percentage Loading Screen. My level is made of a Persistent Level with sub levels for different areas of the main map. When I try to add my main level to a blank level my sub levels don’t show only the Persistent level and not the sub levels. How do I get my Sub Levels to show when I add my main level to a blank level?

My goal is to use three of your BP_Portal Blueprints as my Main Menu. Each Portal would take You to different Levels like Start Game, Continue, Shooting Gallery etc… I would like my loading screen to play a sequencer animation I made which has its own level. I want to use the “skip with any key button” and load my main game level with the Persistent Map with Sub Levels as in picture.

This is being used in my VR game. So I am guessing the any key should work with motion controllers.

Awesome Plugin by the way. Just trying to get this figured out.
