Web link does not display content fully

Hello, i am working on a (test) project to implement Screenly OSE. We have a webpage https://www.koeze.nl/nl/raampresentatie

Everything is up to date, all other pages are well displayed.
link is tested on all major browsers.
Screenly OSE is up2date.

thanks in advance
