Strange light behavior in Enlighten for Unity 4 project imported in Unity 5

I have imported my Unity 4 project in Unity 5 (or 2017) and some models have strange lighting behavior after baking the light maps, these models are the exact same prefab positioned next to each other and the three fridges on the left are much lighter than the 3 on the right.

This behavior happens all over my scene and when I duplicate the lighter models and replace the darker ones the new duplicated model turns darker as well. This model is using the legacy diffuse shader but I also see this happening using the standard shader. Does anyone know what might cause this issue?

My settings for the mesh, material, lights and lighting are:

Usually, this is caused by reflection/light probes that have some of the items in range, but not all. I don’t see any widgets for those on your screenshot, but could there be one nearby offscreen?
