Bugs in content types

I created a new interactive book but when I try to embed it in Blackboard using the embed code it doesn't display.

All other content types display perfectly.

Not sure what is causing this or if others have had issues?

I'm using the h5p plugin on a self hosted wordpress and using chrome browser.

It displays OK usimg the shortcode on wordpress. 

1. Detailed steps to reproduce the bug (exactly how and when did it happen)

I was installing the plugin as per the directions on this site. It installed exactly as planned. And then I started adding the content types as I started to inster an Interactive Content activity in a course. I was successful with no problems on all of the types except 3. I was able to successfully create a Column activity, a Memory Game activity and a Multiple Choice activity. Then, when I tried to create activities of the three types that hung during installation, I got the screens below.
