Can't remove random code from order confirmation page

I added Zippay to my store code, however there is some random code that has appeared in my order confirmation page. This is using the Brooklyn theme. Can someone direct me in the right direction to remove this please?

Thanks

Hi @remylb28
Actually that code will be in additional scripts I think, please remove that from Settings → checkout and scroll to Additional scripts
