Update: I don't know how, but I fixed the issue
For mods affecting npc appearance it would be easier to move another mod that affects serana into a higher load priority because it's likely the appearance mod is overwriting both in the plugins section and in the mod folders section of the textures and meshes due to headmesh generation and ect. So if you have mod 1 and mod 2 loaded in mod organizer 2 for example, and mod 2 makes serana furry and mod 1 is normal looking serana you want mod 1 to be below mod 2 in mod organizer 2 on both the left and right panel so that mod 1 has priority overwriting both.
Alternatively you can delete the serana npc section of mod 2 in sseedit and then delete the associated serana meshes and textures in the mod folders which will have the last few digits of seranas id as the file names.
If you use vortex I have no idea how to use it because I haven't used it before and if you use Nexus mod manager, switch over to mod organizer 2.
I'm using a mod that makes EVERYONE a furry
