Different Levels Sharing same BuiltData

I have two level that share he same built data, even after deleting the built data, resaving both assets, fixing redirectors, renaming both of them, they still share the reference to the same built data asset, and building light in any of them causes the shared asset to get overwritten. Is there a way to change this reference so they don’t share it?
I’m using Unreal 4.27++
