Image Juxtaposition

Unable to uploade H5P content to Moodle powered website

Hello everyone, I am new to H5P and Moodle and therefore might not be able to communicate my problem properly.

There are a few examples that I can use but the ones I'm trying to upload are Image Juxtaposition and Find the words. 

What I do: add new activity → H5P content → upload an H5P content (I previously downloaded the examples from this page) → 'Validating H5P package failed, Missing main library @library
