Object rotation and height

When I upload Gltf file, the rotation and height of the object seems to be off. I used Cesium world terrain and my height is a sea level height. The object is about 150 m higher than it’s supposed to be. Also the rotation of the model is counter clockwise about 90 degree. Anyone noticed things like that? Any idea why?
