Hi OP, have you figured out whats causing the issue, I also have the exact same mods (JK's interior, Lux) in my load order and the exact same issue as yours, are you also using Cabbage enb 1.1 by any chance?
The only solutions I found so far is turn off wetness in enb or just switch to other enb presets or update to cabbage 1.2 version. But cabbage 1.1 is just too good to give up.
I have only notice this issue after I updated a few mods (Lux, Water for ENB, etc).
