Have you installed complete Sexlab and its pre-requisite? Have you run FNIS after install any animation related mod?

Deform body may come from either skeleton or physics. I assume you use up to date XPMSE skeleton and has no any mod override it.

Select either one of them.

Post your mod list.

Either one.

Maybe from other mods ie. Devious Device

Have you install mods as mentioned in steps there?

SLP+ shall be loaded after SL.

You can select particular or "All" armor and rebuild them to your new preset.

Most armor come with body so when you equip the armor that build correctly with Bodyslide, the body will also correct. But the real body when unequip armor are different, you also need to build the nude body in Bodyslide as well. Check in list or armor selected and make sure that you select something like CBBE Body too.

If you update game with Steam, you should have AE version not SE.

You have to make sure all your mods are for the game version you have. Skyrim has many version ie. LE, SE, AE and many mods (include SKSE) have different version for each of game version as well.

Use SOS AE and SKSE that match with AE.

Are you using SLP+?
