Black faces with "principled" material

Some faces of an obj are displayed completely black in Malia and they change depending on the camera left and right rotation (no effect seen on upward and downward rotation).

Base angle:

2 rotations to the right:

2 rotations to the left:

I'm using a material based on a material made by the blender bridge and with updated rgb values.

<material name="Default OBJ" type="principled">
      <base_color>
        <rgb_color b="0.0" g="0.6" r="0.0"/>
      </base_color>
      <roughness value="0.5"/>
      <subsurface value="0.0"/>
      <sheen value="0.0"/>
      <sheenTint value="0.5"/>
      <metallic value="0.0"/>
      <specular value="0.5"/>
      <specularTint value="0.0"/>
      <anisotropic value="0.0"/>
      <clearcoat value="0.0"/>
      <clearcoatGloss value="0.03"/>
    </material>

No black faces were observed with the "green" default lambert material.

I'm using Malia-1.0.0-win64 available here https://pacanows.gitlabpages.inria.fr/MRF/apps/malia/main.md.html

I'm attaching a file with the scene: malia_issue_black_faces.zip
