Problem with opening CityGML files

Hello, i have problem with opening CityGML file, downloaded from Geoportal. I tried open it in QGIS, or convert file to GIS type using FME, but without result. Other CityGML files work fine. What’s wrong with those files? Below is sample. Thanks

Did you try contacting the vendor directly?
