UE4.26 Water not reflecting in glass?

Hey All, I’ve added a custom water body to my scene and I’m trying to get it to reflect in my glass. You can see the reflection in the glass is currently a white plane, its not rendering the water at all. I have ray tracing turned on and can’t seem to figure out how to enable the water’s reflection in the glass. Any ideas??
