Strange results when using Unity Camera and AR Camera together

Hi Guys, I am experimenting with something new. I am trying to use both Unity Camera and AR Camera together in the same scene (Although putting them in different scenes is also giving me the same results).

AR Camera is User Facing in this case. Also, I am building it for Android.

So, here it is output when using only Unity Camera in the scene hierarchy. And when using both ARCamera (Along with usual AR Session Origin and AR Session) and Unity Camera in the scene hierarchy. When AR Camera is World Facing, it works perfectly. Can anyone explain to me why is it like this and how can I fix it.
