Need help with scene component 2D

It looks as though my scene component 2D is not loading meshes at runtime when it is too far away.

I’m trying to have a scene component 2d act as kind of a “headset” for the player but when I’m pressing play it seems to unload all the static meshes that are around. Oddly it only seems to affect the boxes and not the surrounding floors/walls.

As you can see in the above image, I have duplicated the starter content and moved it down. I have also added a scene 2D component within the player blueprint as well as a target material in front of the main camera.

In the preview, you can see the boxes in the scene component but when i press play they disappear as can be seen here:

This thing has been driving me crazy.

Does the plane have collision?
