Water Plugin Post Process Volume Cuts Out Intermittently

Unreal 5.0.3 using Water plugin.

When underwater in a WaterBodyOcean, the post process volume effect will cut out occasionally. This doesn’t seem to happen at any set location or at any predictable interval; the shader just goes clear and there is no effect. It will pop back on just as randomly. Does anyone else have this problem?

I get this when I scale my landscape larger than the standard 100. Did you ever find a solution to this … because I sure as hell haven’t yet.
