Item Spawner Editor Errors

I am getting an error code on half of my item spawners. I do not know how to fix it and because of the error code the item spawners are not showing up in game. When I make new item spawners it doesn’t have this erro. If anyone has any answer what I could do to fix this I would appreciate it. Error Code is below,
Illegal property modification: Property value differs from default: Property: ‘/DuosOGTilted/DuosOGTilted.DuosOGTilted:PersistentLevel.Device_ItemSpawner_V3_C_UAID_2CF05D778B4E61CB01_1969603801.StaticMeshComponent0:bOverrideDistanceFieldSelfShadowBias’ from ‘Class /Script/Engine.StaticMeshComponent’, object type: '/Script/FortniteGame.BaseBuildingStaticMeshComponent’”
