ANM login to Azure AD thru SAML

[Andros]

Hello, I've implemented a SAML SSO login to an Azure AD app.
All seems to work fine (the login form is opened, the credentials correctly validated, and the session authorized from the identity provider), but when it returns to ANM app it gives this error:

Oops
An item with the same key has already been added. Key: http://schemas.microsoft.com/claims/authnmethodsreferences
/login/saml

What can I check to solve?

Looks like there are duplicated attributes from Azure, click Tools -> Update Template to try again.
