RTAO node breaks output in UE Substance 3D plugin

I have a material where I use a RTAO node. In substance designer the material looks correct, but when I import it via Substance 3D Plugin in UE and generate a material from it, the textures are broken.
Here are some examples of Substance Designer:
(Working base color)

(Correct normals)

(Wrong base color after import to UE via Substance 3D Plugin)

(Wrong normals, it is as if the normals have not been calculated further than before the first RTAO node)

When swapping the RTAO with a HBAO node it is working but of course does not have the same look.
I’m using substance designer steam edition:
