Mapbox point tileset not displaying in Unity

I have a point tileset in Mapbox and can select the layer in Unity but the layer does not display and can't work out how to get it to display.

The tileset and style IDs are entered into Unity ok and the name of the tileset is in the list of available layers in the FEATURES section of the Abstract Map but it doesn't display in the map. The other standard Mapbox layers show up ok. Can anyone help with this?,I have a point tileset in Mapbox and can select the layer in Unity but the layer does not display and can't work out how to get it to display.
