multiple warning in back office :(

Good morning.
With the latest updated versions.

I have with this module multiple very annoying and worrying warnings.

example on the back-office in the profile of a user account:

Warning: Undefined array key "admin_form" in /…./public_html/monsite.fr/wp-content/plugins/acf-frontend-form-element/main/frontend/fields/user/class-user-password.php online 64

If I update the profile:

Warning: Undefined array key "_acf_user" in /…./monsite.fr/wp-content/plugins/acf-frontend-form-element/main/frontend/fields/user/class-user-password.php on line 106

Warning: Cannot modify header information - headers already sent by (output started at /…./monsite.fr/aece-pre.fr/wp-content/plugins/acf-frontend-form-element/main/frontend/fields /user/class-user-password.php:106) in /home/sc3sid10/public_html/aece-pre.fr/wp-includes/pluggable.php on line 1427

Warning: Cannot modify header information - headers already sent by (output started at /…./monsite.fr/wp-content/plugins/acf-frontend-form-element/main/frontend/fields/user/class-user -password.php:106) in /home/sc3sid10/public_html/aece-pre.fr/wp-includes/pluggable.php on line 1430

If I refresh the page it gives me this:

Invalid account ID.

Any idea please?

I have the ACF PRO plugin etc…
