H5P content show

Some h5p content doesn't show on first load

I have a wordpress LMS which has WP Rocket. For some reason some H5P content such as interactive videos and voice recording don't show on the fist page load, but on the second or sometimes even on the thir refresing of the page. I don't know if this has to do with the fact that the H5P content is on a woocommerce product page or some setting in WP Rocket.

Here it's an example page: https://www.langcom.org/product/basic-01/

Looking forward to your replies.
