Problem: 2 checkboxes are displayed instead of 1

Hi @p00ch,

It looks like there could be a styling conflict between the site theme and the forms. To fix this, please try the following custom CSS snippet:

.wpforms-form input[type="radio"] + label:before,
.wpforms-form input[type="checkbox"] + label:before {
    display: none !important;
}

And in case it helps, here’s a tutorial from WPBeginner on how to add custom CSS like this to your site.

Hope this helps!
