Flexicontent.css is overwriting css from breezingforms

Hi,

we use fc and breezingforms on our website.
On the url www.tennistraveller.net/blog/287-eure-un...tutzung-wird-belohnt we have a check box next to the label "Ja, ich möchte gerne den TennisTraveller-Newsletter erhalten.
Eine Abmeldung ist jederzeit mit einem Klick möglich."

The check box is inserted from an embedded formular from breezing forms in a fc article.
This check box is not visible because fc is hiding it with the settings from flexicontent.css in line 101:
input[type="checkbox"].fc_checkradio, input[type="radio"].fc_checkradio, [name="adminForm"] input[type="checkbox"]:not(.skip_fccr), [name="adminForm"] input[type="radio"]:not(.skip_fccr), .flexicontent input[type="checkbox"]:not(.skip_fccr), .flexicontent input[type="radio"]:not(.skip_fccr) {

width: 24px !important;
margin: 0 !important;
padding: 0 !important;
opacity: 0 !important;
display: none !important;

I think you can see the problem if you inspect the url and move to the line
<input style="vertical-align: baseline;" class="ff_elem" name="ff_nm_regTTnewsletter[]" value="checked" id="ff_elem596" type="checkbox">

What must we do, that the check box is visible if embedded in a fc article?
It works, if the formular is called directly as you can see here:

Hope you can help us!

Thanks in advance and best regards
Matthias

simply use more important css like this
