Bugs in content types

I'm using the H5P plugin for WordPress.  I can create H5P content, but depending on where I place it on my WordPress page, it sometimes does not display (I see only a blank space where the H5P content should be).  The H5P content appears fine on its own or within some other shortcodes, such as the accordion shortcode.  For example, the code below displays the H5P content fine:

[accordions collapsible=false active=true style=accordion-container]
[accordion title="Title" style=""]
[h5p id="1"]
[/accordion]
[/accordions]

Dialog Cards > Behavioural settings > Scale the text to fit inside the card.

This option makes it possible to resize a longish text to fit inside a card. Of course, a longish text then has such a tiny font that it becomes illegible, and of course the Dialog Cards activity is not supposed to consist of longish texts. However, for the purpose of crash-testing this activity (!) I have found the following bug.

Create a Dialog Cards activity with at least 2 cards. In Card 1 insert a long text. Check Behavioural settings > Scale the text to fit inside the card.

I updated my Drupal instance's h5p libraries and upgraded content and now I cannot save edits.  I was using official-h5p-release-20160802 along with updates to course-presentation, and a couple of other libraries.  All was working great before I updated the interactive video and video libraries to the latest to correct the iphone 7 full screen issue.  Worked great locally, could view content, full screen issue was corrected.  We later noticed as we neared production that after converting content we could no longer edit and save.
