Pageloader doesn't work properly on exported site


So I have made a website in Webflow, which I needed to export for use in Umbraco. Verything seems to work, except for the page loader, which does it’s job on the Homepage (index), but on other pages it freezes on the ‘loading’ state. So when the page loads, you only see the pageloader, which doesnt disappear when the page is fully loaded. Does this have anything to do with ID’s of certain elements?

Also, I’m not sure if I posted this in the right Category, so be free to direct me!

Thanks in advance.
