Depth Causing Problems For Certain Models

[ipsen413]

I'm having issues with certain models when I activate depth occlusion in my Android Studio project. The occlusion works correctly but now the models are getting stuck halfway in the floor. This is happening on every model I try to import into the program, however everything seems to work fine with the model used in the SceneView Depth example program (Giant Panda). Here are some screenshots of what I mean:

I've looked for a solution everywhere and have tried repositioning the models programmatically but so far nothing produces any change. If I turn off depth occlusion then all models appear on top of the floor correctly.

Any possible solution to try out would be greatly appreciated. Thank you in advance for your help.
