Packed texture help

I haven’t encountered and was wondering if somebody could offer some insight. I’m using Substance Painter and per norm, it shoots out a packed texture for the Occlusion/Roughness/Metallic. Nothing out of the ordinary. When I import it into UE4, it for some reason, imports as a Normal map. I changed the compression settings but that didn’t work either. Anyone know what the problem may be? Would it be on the Substance side or Unreal side?
