Cannot see Floorspacejs

edit

I am opening an OSM file, it has everything but the geometry of the model made. The JSON file is in the file folder and I can see the 3D view. I even checked the file on the https://nrel.github.io/floorspace.js/ website, it opens there and works fine.

When I press the editor tab, it only shows the Overview of the different files like FloorspaceJS, gbXML, IDF, etc.
