Conditional field problem when mandatory or optional

Hello,
In my form, depending on the age of the user, the email field is mandatory or optional.
So I created a condition to display the mandatory or optional fields depending on the age.

[checkbox eleve use_label_element exclusive “Mineur ” “Majeur”]

[group elevemineur]
Email : [email email]
[/group]

[group elevemajeur]
Email* : [email* email]
[/group]

The display works correctly but the code does not work, the email field is considered optional regardless of the age chosen (minor or adult).

The asterisk (*) of [email* email] is not taken into account.

Of course, I can create two different names email_minor and email_major but I need to have a single item for display in a single column of a table afterwards.

Do you have an idea to solve this problem?
