T&C coming back for authenticated users

Hello,

I have a problem with Legal module. When I am administrator, the module is working fine, once accepted, I do not have to accept again on new login.
But for authenticated users, the T&C are always coming back at any attempt. If I accept, then I am logged and can work ... but on a new visit I will be prompted again for T&C.

Did I miss any configuration ?

Thanks in advance
