too much white space

So, I’m just starting to use this awesome plugin, and I have made a testing page to get a feel for it before deploying it. I’m appearing to have some formatting issues, as there is a LOT of white space in the front end form. I tried looking over the css, but couldn’t locate what’s going on here. Can someone take a look and help?

Here’s the page: https://uhpsichi.org/index.php/test-tutor-request/

(BTW, I really like the plugin thus far, as this is for a student organization offering free tutoring, and I wasn’t expecting to find a plugin this versatile and free. Since we obviously have limited funds, this is pretty great for us!)
