Popup subscription form issue

Hello,

I added popup subscription form (inbuilt in popup maker) with
[pum_sub_form name_field_type="first_last" disable_labels label_submit="Subscribe" placeholder_fname="First Name" placeholder_lname="Last Name" placeholder_email="Email" form_layout="block" form_alignment="left" form_style="default" privacy_consent_enabled="yes" privacy_consent_label="Notify me about related content and special offers." privacy_consent_required privacy_consent_type="radio" privacy_consent_radio_layout="inline" privacy_consent_yes_label="Yes" privacy_consent_no_label="No" privacy_usage_text="If you opt in above we use this information send related content, discounts and other special offers." closepopup closedelay="0" openpopup openpopup_id="0"]

When I click on consent “NO” it gives me error “Email provided is not a valid email address.” and also there is no any email restriction, duplicate email entry possible.

Need solutions.

Thanks in advance.
