Prefab brush with y as z tilemap issues

Unity Engine
1

I’m trying to use a prefab brush to place an object on my tile map, but it renders under all the tiles I placed.

what I have tried

:creating a new tile map for objects and making the it higher on both the hierarchy and the z axis
:adding a Colldier to the lower tile-maps

Just to check, what components are on the Prefab you are painting? Are they SpriteRenderers?

Yes it is a sprite renderer
