I have noticed that the external unity plugin TexMeshPro is used for geo-names. In your particular case looks like the mesh drowns under the planet surface.
In addition, this TexMeshPro doesn't seem to cope with non-latin unicode symbols, and there is a post about it in this forum.
For me the standard Unity Projector looks like a good alternative for that, but I may be wrong.
