You should uncheck it, or remove it completely since it's just duplicated, old, files. Make sure to toggle them on in SLAL and then register the new ones there, for SexLab to recognize it.

Install https://www.nexusmods.com/skyrimspecialedition/mods/19250 Open console and click on the trapdoor. It may show which mod is editting it.

The Eyes of Beauty

It's actually ECE head mesh.

I second Silent Horizon. The default gives you a very good balanced and colorful look. You can always tweak it a little for your preference. You can also use LUTs with it which will drastically change the colors if you want some different settings for screenarchery.

I use Silent Horizons ENB.

If you used MergePlugins it will create a new ESP with the merged esps. You should then disable the original ESPs and just active this new merged one. But remember that you still need the original mod data files, like meshes, textures, etc, active. In MO you can right click in a mod, click Information -> Optional ESPs, and move the ESP there. It will hide the ESP from showing in the availables ESPs to toggle active or not. Alternatively, you can mark your weapons / armors mods as ESPFE using xEdit. Or openning it in CK and resaving them as ESL. The limit for those are much higher than normal ESPs. (This is for SE Only though)

Did you install the [OPTIONAL] WickedWhims Censorship-Streamer Mode?
