AI Avatar facial expressions deadpanning at inconvenient times.

Hello, I keep running into my AI Avatars (which I love) making really mean looking facial expressions at the end of their talking. I have tried rephrasing, different avatars, and it isn’t helping. Has anyone had luck or any suggestions on how I can get her to smile? This is for a new employee orientation video and frankly I don’t feel welcome 😂
