MailPoet shows large overlay and no forms on homepage

Hello!

I’m working on this site, https://campbell.dk/, and one of the issues is an overlay showing instead of the popup form. It mainly shows in incognito mode, but sometimes it shows on regular browsing. It takes a few seconds before it shows up, which first allows the user to interact with the site, but quickly renders the site unusable. What do I do? I’ve checked all settings for an overlay setting, but there’s nothing of the sorts. Chrome inspect elements shows it’s MailPoet, but I’ve tried turning all the forms off, yet the overlay still appears. However, sometimes the actual form shows up, though this is very rare, and I have no idea how to replicate the actual form showing up. I’ve now tried for days before opening this ticket here.

Best regards,
