Export 2D texture map not working correctly

[Stoff1979]

Hello, im running into problems with 2D exports. My exported texture doesnt look like the 2D view in Substance Painter, Normal Map is missing and also the lightning is totally different. It only happens when using PBR Metallic Rougness Shader! Not with PBR Spec/Gloss shader. Im on MacOs. Any ideas?
