Behavior is not being used

[ssong0011]

Hello 🙂
Through Adobe Character Animator
We have created a Puppet.
But as you can see in the red box part of the attached picture
It says that 'behavior' in the 'mouth' group is not currently in use.
Please let me know how I can solve this problem.

It appears that you are using a swap set with a trigger for the mouth expressions. Are those mouth sets working for you? If not, try adding the mouth behavior to the Mouth layer.
