Dialog Cards Editor | missing add and edit fields in Moodle 3.5.3+

Dialog Cards (1.8.2)

Updated Dialog cards to version 1.8.2 via the update prompt when adding New H5P content to a course. I selected to use the content type and noticed the fields for adding words, sounds, images and cards were now missing (as in the attached screenshot). Used it a lot until now with no issues as the H5P Libraries show 143 instances of the content type being used.

Previous instances:

Previous instances still work, until you try to edit them. They also show the blank editor with no content. When you save and display the content area is also blank except for the heading and return button. When you go back into edit, select a different content type, confirm when getting the warning message, and go back to Dialog cards, previously saved content will display as normal in the editor. Once saved you still get a blank screen.
