Donorbox Embed form not aligned correctly

Hey All,

I’m having trouble with an embedded from from You can see it when visiting 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.

Any help would be amazing!!
