Curious how you post all those screenshots but not the information I asked for:
The double rotor is placed by the vanilla reference 0007ADFD?
It uses the base record 00050C57 that defines the model swindmill.nif?
None of these record are overwritten by plugins?
The swindmill.nif is from Skyrim Meshes0.bsa
DynDOLOD.esp should be overwriting the base record 00050C57 and add alternate textures to replace the rotor textures with null textures to make it invisible.
Typically users use the unofficial patch, so I would have assumed SWindMill.nif to be from Unofficial Skyrim Special Edition Patch.bsa. Either way is fine.
Double check those things.
