The player is looking to positing a set of a table and 4 chairs into a room.
The player selects the dining set.
The player is presented with a holographic 3d preview of the models that he can move around for placement preview, then clicks to spawn the objects in place.
The BP of the table set has 5 meshes inside of it, the table and 4 chairs.
Currently the BP in charge of the hologram preview is pulling the 5 meshes from the TABLE SET BP, but overriding each other instead of pulling them in and adding each one to the preview location. therefore only the last mesh is displayed for the player.
