Pop-up form WON'T scroll, Please HELP!

Hello Webflow Experts!

I have created a form that is triggered on multiple pages by the button “REQUEST SAMPLES”, it looks great on large screens however when on smaller screens the scroll is working rather odd. I have two scroll bars and I still can’t see the entire form using the scroll bar. I have the form’s overflow on auto like my other forms and the parent element is fixed. I feel like it has something to do with how the overflow is set, am I supposed to make the parent elements overflow hidden?
