Hello,
When you use image and picture side by side in course presentation it causes a bug that text editor field doesn't open properly under certain conditions.

Steps to repeat:

1. Create a new course presentation to h5p content bank
2. add text element to the left side of the slide and picture to the right side
3. expand then so they cover 50%/50% of the slide
4. duplicate the slide
5. save
6. go to edit the created course presentation again
7. click the text-item on the first slide and select done
8. open second slide and doubleclick text-element
9. notice how text-editor doesn't open/work.
