Unchecking/disabling ldap_allow_unauthenticated odes not work

[TRoc81]

Describe the bug
I am trying to disable the ldap_allow_unauthenticated option, which is enabled by default when creating a new LDAP authentication server.
I can re-enable it after manually disabling the option.
Same with ldap_rfc2307, but this option is not enabled by default.
I can enable both by setting them to true in the playbook, but cannot disable them by setting them to false in the playbook.

There is no error when running the playbook.
I tried FALSE, false, False, "FALSE", "false" and "False".

Expected behavior
Options will either be checked when setting them to true or unchecked when setting them to false in the playbook.

Playbook
Please paste a minimal playbook to reproduce the issue:

    - name: Add adservers authentication server
      pfsensible.core.pfsense_authserver_ldap:
        name: AD
        host: adserver.example.com
        port: 636
        transport: ssl
        scope: subtree
        authcn: cn=users
        basedn: dc=example,dc=com
        binddn: cn=bind,ou=Service Accounts,dc=example,dc=com
        bindpw: "password"
        attr_user: samAccountName
        attr_member: memberOf
        attr_groupobj: group
        ldap_allow_unauthenticated: false
        state: present
