Forms Checkboxes issue with latest update

I use Formidable Forms. Since the last Enfold update, all of the check boxes had issues and I added the following code to the Formidable css and Enfold’s Quick css
#top input[type=”checkbox”] {
display: inline-block !important;
}
This solved the issue of the check boxes appearing as a tiny line to a normal check box. However, now when you fill out a form, the check inside the check box is not visible.

I was told by formidable:
“I found that line on a file called avia-merged-styles-3153472f915df5917fbf7b8de27b8edd.css, but as I am not familiar with your theme or set up, I cannot tell you which file has that line — as that file I mentioned is probably just a merged minified one.

You could try adding this to the style on Formidable Forms:

#top input[type=”checkbox”] {
display: inline-block !important;
}
But I cannot guarantee that it will work.”
This is the location of the form: http://www.fwhcsl.com/tournaments/register/
