image pairing

I would love to upload Image Pairing but on both of the examples when I 'reuse' and try to upload I get Missing required library H5P.ImagePair 1.4Get help /  I have found this to be a problem on most content types.  Is there something I am doing wrong?  Thanks!

你好，

我在网站上创建了许多图片匹配文件，

下载后，有些可以上传到新网站，有些则不能，请帮助我看看发生了什么。（我们所有图片均为PNG或JPG格式。）

附加可上传文件和不可上传文件。

Image Pairing has a bug in the handling on mobile devices. I noticed it on the iPhone, I couldn't test it on Android.

Testet on iPhone X with iOS 13.5. in Safari
