Outliner Not working with prefabs after switching scenes

Hello! I am using the simple outliner script from the unity asset store
it works amazing, when Outlining a prefab with multiple meshes it also works like a charm however when switching scenes then using it, it somehow messes with it and only one mesh out of the the prefab gets outlined

for example if i start the game scene it works fine however if i go from the menu to the game screen it breaks
this also happens after build, I am not too sure what is happening screenshots added below:
