Problem integration avatar Community builder-Komento

Hello guys from italy, i have a problem with the component, in particular with integration of the avatar of community builder with komento. I use at the moment version free and i'm interested to version pro but with this problem no. I put in backend, integration with community builder but all avatar people of the website have for default gravatar and is impossible to change this option. Also in the module.
Thanks for the help, greetings from italy
