[SOLVED] Poses flipped horizontally in CAS vs. Blender

I'm trying to make a CAS posepack that uses the "styled look" poses, because I think they're cute. I exported all the poses, merged them all into one continuous pose in Blender just like I've done previously... but when I go into CAS and select the trait, everything's flipped horizontally! The poses themselves? Just fine. But they're all flipped from what they should be, which is annoying. Is there a way to fix this?
