Left Eyebrow Rotating, Eyes Messed Up

My puppet's left eyebrow rotates and eyes go weird when in play mode, but all looks fine if I click Stop.

After the first 15 seconds of playing, the face behaves as it should the rest of the video.

Both eyebrows are set up as independent (Crown) in Rig mode. The lighting was the same for all recording with the laptop's camera.

I followed the instructions on Okay Samurai's Limb IK video to create a secondary Face behavior under the Head group. Then at the Puppet layer, renamed the original Face group to Body (except there was already a Body behavior there, since Body/Limb IK/Motion Library all need to be enabled). So I named it Body 2.

Any ideas how to fix it?

Thanks!
