Strange Normals on Export

So I was doing some experimenting and exported the default avatar with the following export settings:
60% of original size (was 846x459) - Click to enlarge

However, when I imported the character into 3ds max, I noticed the normals on some areas of the character's body were seemingly flipped.

Note the square patch in the lower-right window.  This also showed up when I imported into Unity3d.  It was fixed if I chose to calculate normals instead of import.

Additionally, this was fixed when I used the merge UV export functionality.  Anyone else run into this issue?

Thanks for the feedback. This has been passed to the CC3 team to investigate.

UPDATE: Please can you refer to the forum post below. We believe this may be related to this issue in 3DS Max.

Hi! No it isnt just a 3d max problem. I noticed exactly this when i exported the default woman to ue4. Some polys are messed up, for example on the legs. Thought is was a smoothing group issue...
Please fix this. Best regards,
michael

Can you post a screenshot showing the issue in UE4. Thanks.
