Multiple Choice

I tried this on 2 H5P servers and i noticed that when creating multimedia choice activity the last card of the in the row is slightly bigger.
if i set 4 cards in a row - it's always the 4th one, and if i set 3 - it's always the 3rd.

is it a known issue? 
if it's only on my side - how come it happens in two different institution i work for? 

I added two screenshot and a file 

<p>The right column of images in exaple https://h5p.org/content-types/image-choice has a different size than the others. The same issue occurs when uploading h5p-file to Moodle 4.5.4.

Hi there, 

One of our academics is using MCQs, some with multiple answers, in an H5P Course Presentation. 

For the questions that have multiple answers, she would like students to retry the question if they get it wrong. However, the default settings are such that if students tick all the boxes, they can see which are correct and which are incorrect - so there is no point retrying the question. 

Is there a way of creating multiple-answer questions where you don't see the correct answers until you've chosen only them?
