css conflict with wcvendors pro in opera, firefox and IE

Hi

I am using customizr with the wc vendors pro plugin. Everything is laid out beautifully excepct some of the forms created by the plugin, and that is only in the browsers of firefox and opera. The plugin authers cannot recreate the problem on their dev server and I have disabled all other plugins.

I isolated this css, which is actually from the plugin and tried to override it within customizer, using firstly the inbuilt custom css and then adding to the childs css. However this does not seem to work, so I need some help. does anyone know what I need to do.

This is the css I isolated and changed

.wcv-form input[type=”week”], .wcv-form select, .wcv-form textarea {
font-family: Arial,Helvetica,sans-serif;
font-weight: 300;
border-radius: 2px;
padding: 8px 6px;
padding-top: 8px;
padding-right: 6px;
padding-bottom: 8px;
padding-left: 6px;

when I change the padding from 8px to 0px everything is fine in the firebug but I can’t make it stick in the custom css.

Can anyone help
