Skyrim SE: water reflecting sky in cave with ENB on

[TomForEnb]

I have stumbled upon this issue: in the East Empire Warehouse (in a cave without roof below Solitude), the water is reflecting what looks like the sky with ENB turned on. With ENB turned off, the water is dark as it should be I guess. See screenshot with ENB on. What could be the reason for this behaviour?

I use the latest files from version 0.479 with Rudy's Cathedral ENB.

I don't see issue myself, but on discord got asnwer "that's an exterior interior cell, possibly that's the reason". Solution is unknown to me.

Thank you for your fast answer. Ah, interesting, it is indeed not an interior cell, but a worldspace...

As I already use Rudy's Cathedral ENB with different ENB settings for weathers and locations: would it possible to add an additional enbseries .ini for this location and configure its ENB settings accordingly to reduce the sky reflection?
If yes, how can I assign a .ini to a specific location? I have tried to find out, but haven't found out yet how to do that.

This requires to enable per location weather and create such. But i don't remember how this feature works and how to setup it.
