We have multifloored building data in geojson format of different cities and we want them to be rendered at the front end as cesium tileset using cesium JS API.

I am facing issue with conversion of geojson data to cesium 3D tiles. I have tried converting geojson to cesium 3D tiles using FME software. When I convert using FME, some of the faces of buildings are missing (shown in the attached images). I have explored over web as well as cesium community, but I found cesium has built in tool for such conversion. Kindly guide me if something missing in that conversion or any specific tool required for such conversion.  
I have attached images of geojson data as well as cesium 3d tileset data from all sides of the building.
