Gravity Forms styling issue – please help

Hey

I have two issues with my gravity form. I contacted them but they said it was a problem with my theme’s styling and my theme isn’t answering. My first issue is that the form has a giant space at the top that I can’t seem to get rid of for the life of me.

But the major issue is that when you fill out the form and click the next button all of the content displays on the far right side of the screen, so you can’t see it at all. And it seems to be almost random, sometimes I can get it to look okay, centred on the screen, although I’d rather have it aligned to the left, but other times it freaks out and goes to the right side of the page again. I’ve tried a lot of different things to try and fix this but I’m at a loss. If anyone could help I’d really appreciate it.

The form is here: http://www.isae2016.ca/abstracts/
