prestashop official gdpr module consent checkbox not working

[merit]

Hi all, after update from 1.7.6.7 to 1.7.6.8 I have an issue with consent checkbox in contact form and newsletter subscription module. Send button works even without mark chechboxes, while it works perfectly in the customer registration form. I have try to downgrade contactform module from 4.3.0 to 4.2.0 but nothing. It seems to be something missing.

 

1.7.6.7:     <button class="btn btn-outline float-xs-right" name="submitNewsletter" type="submit" value="Subscribe" disabled="disabled">
                  <span>SUBSCRIBE</span>
                  </button>

 

 

1.7.6.8:   <button class="btn btn-outline float-xs-right" name="submitNewsletter" type="submit" value="Subscribe">
                <span>SUBSCRIBE</span>
                </button>
