Room Generation part 2

How do I…

Hello, I made a post like this one, but it wasn’t helping me. Anyways, when making rooms generate.

What is the expected result

Its suppose to generate the rooms at the positions that they are suppose to be at. Like the furniture its suppose to generate in the spot it is at when the room generates.

What is the actual result

It gets really confusing, and the reason is the because the rooms are multiple objects compiled together

And because of this, I tried making them object groups, but when I generate the rooms, they all come to the middle of where they were suppose to generate. Please help me figure it out, I have no idea how to do it. Do I have make a room just one object, and maybe make something else that helps to make tables generate ingame?
