Very huge footer on Squarespace 7.1

Hi there, 

Would anyone be able to shed a light on this? We are currently working on univastgoed.squarespace.com (not finished yet), for some kind of reason the footer is huge. When we're in editor mode, it seems to be perfect, but whenever we check it in a browser it just seems to add a lot padding, which is not how it should be? 

Anyone have an idea what is causing this? 
Thank you! 🙏

I can't tell what is causing the space, but my guess is that it's caused by one of the scripts you have running.
