It's a wrong initial value coordinates on the yOffsetA OriginY hip actor channel that cause the problem, it differs from the origin coordinates when both should be identical.

Poser File editor by Dimension 3D can auto correct actor offsets, thank God this issue can be fixed in one click.

The problem comes even before saving the CR2 in library after leaving the setup room so I guess there is something wrong in the setup of the conforming clothing by PP2012.
