Fancybox Lightbox not appearing right on membership plugin

Hi there,

So I am loving the plugin. Just a question about the popup lightbox. So when you go to hunterscabin.co.nz/hunt/register and click sign up, everything works alright. But when it goes to the next pop up, where it shows you the payment options, the lightbox doesn't stretch to 100% and the content overflows the box and it looks really average because of this.

I have tried to troubleshoot it through CSS and JS for the last couple of hours but can't find a way to get rid of the inline style under "fancybox-wrap" which seems to be the main issue. It changes it to 724px and when I use inspect element on chrome and remove this style it works fine.

I have included a screenshot to show what I mean.

Thanks for your help,
Dylan.
