Course Presentation

I'm looking for direction on sizing a drag and drop activity within the Course Presentation tool so that it fits.

I've created a drag and drop activity within the Course Presentation tool but when I view the presentation the drag and drop content is outside the boundary of the Course Presentation canvas so there is a scroll bar on the right (see attached screenshot).

Kia ora, we've been building a workshop and H5P and think its amazing.  We're stuck on how to include the video content into the course though.  We are using vimeo.  I've read a lot of the forum comments on this but they're very old, mostly seem to be discussing interactive videos (which we arent using at this stage) and I can't tell if the language / account types have changed, if its actually a totally different thing, or what.

Some content types, even though available and working in the content bank, gives the following error when trying to access from the content bank: 

invalid-library-json-file : Could not find library.json file with valid json format for library filesaver-1.0
