Sub Scenes Cannot Render Tilemaps(?)

Hi, in the last few days I tried to play around with ecs, I was able to render tilemaps and sprites using the convert to entity script set on the inject option, this works very nice unless you try and use the scene as a subscene, I get no errors but the sprites or the tilemaps just dont show.

Am I missing something ?

 

Up, what is the current state of this?

 

has anyone found a way to do this? can't find any other documentation talking about this. need help
