Cannot see gameobjects in Unity editor (DOTS problem)

I am using the latest project tiny boiler plate code (Tiny2D)

Unity Version: 2020.1.17f1

DOTS Runtime 0.32.0-preview.54

DOTS Editor 0.12.0-preview.6

Entities 0.17.0-preview.42

Hybrid Renderer 0.11.0-preview.44

I cannot see my gameobjects inside of the scene view, in the unity editor. These gameobjects work perfectly fine when I compile the code and run the game, I just can't see them in the unity editor.

I have already tried other fixes like: https://answers.unity.com/questions/1332472/cant-see-gameobjects-in-scene-view.html

The closest thing to fixing my problems is this solution: https://answers.unity.com/questions/160923/objects-disappear-after-building.html During the part where the OP says " managed to fix it. I still don't quite know why it does that or why what I did fixed it, but I'm glad it did...."

Here is a picture of my gameobjects in the scene view:

I am working on a project that uses project tiny, and DOTS.

Watch what happens when I move "MainMenu" outside of the DOTS scene:

They become visible again! (from inside the unity editor)

What's going on? Why are these gameobjects invisible while they are inside of the DOTS_Scene vs MainMenu?
