Static Model Hidden Automatically

I have a room asset, that’s part of a FBX model I download from the internet. The door of the room sometimes vanishes automatically when I look at it from certain angles. It’s not a near/far plane clipping issue as models behind and in front of it are being rendered well. Any idea why that’s happening?
Thanks.

Maybe something with bounding box.

If mesh not inside bounds, or attached to other object and uses its bounds, it will not render when bounds are outside camera frustrum.

You can show bounds in static mesh editor or in level and check
