If you open up a new project, and load in a scene through the addressable, the scene will only have its contents if it is at the root of the project folder
Here you can see that its working on the first one which has the scene at the root folder where the second one has the scene empty and its in a folder.
My unity version is 2019.3.0b12, package version is 1.1.10
On a side note, the path doesnt update when you change the location of the asset through the projects folder. Which is very annoying because I need to set and reset the addressable check box every time I move an asset
