Double authentication with Community builder. - by: poltec

hello,
When the user is not connected and want to register in a training session I forced him to create an account or authenticate.
If it is already known and that it wants to authenticate then on the submit of the eventsBooking login page, it is redirected to the CB login page...

How to avoid this double authentication?

Thanks in advance.

Kind regards.
