Nintex Form formating issue/css issue

 Good afternoon,

I've been having a problem with Nintex forms for some time that I can't solve on my own. My forms always render missing the right side boarder (see pic).

I suspect the issue is in the CSS (below) but I don't know enough for me to determine if this is in fact the issue. I have pasted the CSS below.

Any help would be appreciated.
