AGOL buildingexplorer. Can't show all the layers of my 3D Models at once, only 1 model at the same time

I have 2 3D models in my scene. I want to show all the layers of these models but for some reason I can only see all the layers of 1 model at the same time. I think it has to do with the building explorer tool. When I click on the tool and then on a model. It shows all the layers of this model but doesn’t show all the layers of the other model.

Above: How it is normally shown

Below: When I select this building, all the layers show. But the other model has just 1 layer visible instead all of them
