Can't edit pose (locked gaze)

Portland

I imported a pose and tried to make my character to look down. But the head tilted back up as soon as I'm out of the Blender Pose mode. It seems like the gaze is locked on to the camera. Not sure if it's Blender or some bone drivers option I have to change. I tried 'Transfer eye to gaze' and 'gaze to eye', uncheck rotation locks and disable drivers. None seems to be doing anything. I'm using a converted riggify armature option from Diffeomorphic if that matters. Any idea on how to fix this?

Nevermind. Somehow, there's a keyframe inserted. I just need to re-insert/update with a new keyframe. Not sure how the keyframe got there in the first place.
