Hi Eric,
A fix will be available in the next update. In the meanwhile, there is a simpler work around to avoid this issue.
Simply switch to SOLO grading mode (by unchecking the ‘Link’ icon on the Stereo 3D tab), make any changes that you need to make in the camera RAW settings, and then switch back to GANG grading mode.
