Hidding the CC field on a contact form

For some reason on a new form, both a CC field and Organization field are both showing up. I cannot find a way to remove them in the admin center, but I would like to hide, at least the CC field. The below lines have disabled the field and hidden the label, but there is still a visible text box that cannot be edited and it looks like butt. How might I be able to hide this unsightly thing from my users? The field is contained in this snippet:

<ul tabindex="-1" data-hc-pills-container="true" data-hc-focus="false"><li><span style="display: none; width: auto; white-space: nowrap;">Add emails</span><input type="text" id="request_collaborators_" value="" autocomplete="off" aria-required="false" aria-describedby="request_collaborators_error" style="display: none; width: 122.6px;" placeholder="Add emails" size="23"></li></ul>
