Glass reflects the window itself
In my small project, I was following the official documentation for glass material. But in the result, in the glass's reflection, you can see the glass and the window itself, which would make no sense at all.
Here is the screen shot:
That looks like refraction not reflection. You'll want to mess with Refraction Depth Bias if that's the case.

I have experienced really weird tearing like this with glass in unreal myself. I ended up following this tutorial to create a much more custom glass shader that allowed me to control the reflection and refraction much more to fix the reflection/refraction tearing
Also check your reflection probe locations and size
