Donorbox Embed form not aligned correctly

Hey All,

I’m having trouble with an embedded from from donorbox.org. You can see it when visiting https://anima-lefkada.webflow.io/ and clicking on “Donate Now” in the menu bar . I have set it so that the form appears as a popup, however for some reason the form appears aligned to the top of the page and is also the width is slightly compressed (see screenshot). I can’t figure out how to fix either of these issues.

My read only link is here: Webflow - Anima Lefkada

Any help would be amazing!!
