Static Mesh actor doesnt appear on top of image tracked

[rehanahmad608]

Hi, i am new to unreal engine and working on arcore. I am using arcore sdk version 1.6.0 with unreal engine 4.22. Trying to implement augmented images sample project. I have made my own static mesh actor and my own candidate image. i have made necessary changes in blueprint like in spawnactor class to my own static mesh actor. When i run the application it shows that image is tracking but nothing appears on top of it. i am testing on Samsung galaxy S8 running android version 9.
