iFrame Embed Widget yields different widths, same specs

Hi there. I have two iFrame Embed Widgets in my form, and as far as I can tell, they are both set up the same way width-wise. Yet when I do a preview, one of them is too narrow. Can you help me fix this so that they are both the wider width? Thank you!

I've made an adjustment in the base form and that seems fixed the problem. However, the forms are cut off at the right side. I think you need to adjust the width of the base form to match with the forms in the iframe widget. Or, adjust the width of the two forms in the iframe widget. 

To add, all forms has 580px width. I would suggest adjusting the width of the base form (http://www.jotform.com/60006441268953). Try setting up 600 or 650.
