Mapbox vector tile MVT is missing data

I'm trying to make my own renderer for Mapbox MVT vector tiles, but I have hit the obstacle and couldn't find the answer. My problem is that MVT tile downloaded form Mapbox server contains all roads, but only a few bulding numbers (should be much more for given area) and no land types (grean area on map) and buildings.

Anyone had same problem or know the answer?

link I use to download tile is: https://api.mapbox.com/v4/mapbox.mapbox-terrain-v2,mapbox.mapbox-streets-v7/18/143415/87627.mvt?access_token={access_token}

Below raster tile for the same area:

The trick is in decoding MVT tiles (using mapbox-vector-tile-java), to parse it properly MvtReader.RING_CLASSIFIER_V1 needs to be used:

final JtsMvt result = MvtReader.loadMvt(f, new GeometryFactory(), new TagKeyValueMapConverter(), MvtReader.RING_CLASSIFIER_V1);
