Has anyone encountered and resolved the error pictured below, when using FloorspaceJS in the OpenStudio interface? It occurs after I add a floor multiplier and merge with the OSM. The message itself doesn't offer much insight - is it literal? Am I simply not giving it enough time to apply the multiplier to the geometry?

Additionally, once the multiplier is used, are all floors visible in the the editor window? I've not actually seen it functioning correctly yet.

Thanks
