Visual Glitch: "Double Vision" texture and blackspot

UE 5.0
Hello, Im having two visual glitches when importing a 3DS Max file via Datasmith from my friend.
There seems to be a weird…inclined(that becomes shallower/flatter when I go closer to the floor) double vision.
Another is a blackspot. I think the blackspot I can cover it up but any advice would be appreciated.
The “Double Vision” is the visual bug that I have no idea how to resolve, any one knows what to do? Cheers!


So I realized that loading my Datasmith package in UE Film template looks perfectly fine whereas in here its all screwed up. After some troubleshooting, removing the Refraction component in the material removes this visual glitch (but looks more plain than in the Film template). Any idea how I can have the same visual quality as in the Film template but using the VR template instead?
