3D Tileset below generated Terrain


I tried to generate a terrain using terrain tiler, and I have used it on my 3d tileset, but why is it below or in the middle of the terrain and doesnt stick to the top of the terrain?

Is there a parameter that I should pass in the terrain tiler or point cloud tiler to avoid these kind of issues?

My issue has been resolved, for some reasons I loaded an invalid terrain thus resulting into this weird behavior.
