P: Issue with 3D Lenticular stereo image generation (works fine in CC 2014)

Photoshop CC 2015 appears to have a major bug with lenticular stereo image generation (the same feature works fine in CC 2014 so the bug has only been introduced in the latest version). The bug can be replicated by creating any 3D scene (by loading a 3D model or converting an image to a 3D postcard) and then turning on stereo in the "Current View" panel and choosing Lenticular (and a depth or distance above 0). The lenticular interlacing that is generated in CC 2015 is always 1 pixel wide irrespective of the LPI setting. For example with a 600 DPI image and a 40 LPI setting the vertical interlacing should be 15 pixels wide, but is only 1 pixel wide. Changing the LPI value has no effect on this either. This makes it completely impossible to generate lenticular stereo images for printing in the latest version of Photoshop, which is critical for my business.
Please advise if this bug can be looked at and resolved (maybe the code can be reverted to that in CC 2014?).
Thanks.
