Light reflecting in far away water

Bit of an odd one. The ceiling lights are reflecting in the lake which is around 7km away! This only happens when the window is in place. I’m using Waterline Pro for my water material. I’m using Lumen, ray traced reflections etc and have played with a bunch of settings including reflection, translucency and sort order. Any thoughts on what this could be?

After a lot of messing around to try and fix this I gave up and used a metallic texture with a water ripple normal map with a planar reflection. I followed this tutorial.
