NX Some faces exported from TDP is not rendered

When exporting a 3D PDF and opening it in Acrobat Reader, some of the faces lose rendering. Are there display settings that affect this?

Reproduced Steps:

1. Create a sheet body(e.g. with Extrude)

2. PMI tab > Technical Data Package group > Publish

3. Open the PDF in Acrobat Reader

Conforming Preferences in Acrobat Reader:

Menu >Preferences > Multimedia & 3D > Enable double-slided rendering＝ON

***If OFF, one side of the face will not be rendered. In this case, enable double-sided rendering.
