My suggestions:

  1. Check the constraints for flipping on the controllers parents. If it is “Average” set it to “Shortest”.

  2. Try setting any wireDeformer falloff higher. This might not be related at all, but it helped me with some eyelid problems: Eye rig does not work the right way when I scale the character - #5 by chrislesage

  3. Share your lips configuration file from the facial rigger tool. A screenshot, or paste the JSON code here.

(your file is not accessible on google drive.)

Thank you for fast reply and pointing to wire Deformer . After setting wireDeformer scale to 0 lips stopped deforming during Z rotation!
