The sign-up buttons for social connections are not displayed on the signup-id screen

I would like to ask one question regarding the Auth0 signup-id screen.

When the signup-id screen is displayed initially, the signup buttons for social connections are shown.
However, after proceeding to the next screen once and then returning to the signup-id screen by clicking “Go back” the sign-up buttons for social connections are no longer displayed.
I would like to confirm whether this difference is due to the product specification or to some particular condition.

I would prefer that the sign-up buttons for social connections also be displayed when returning to the signup-id screen after proceeding to the next screen once and clicking “Go back” If you know how to achieve this, I would appreciate your guidance.
