Scoring in multiple choice affected if answers not submitted
I have an interactive video, with multiple choice interactions. I've noticed that if the learner does not submit their answers, it does not record these against the gradebook, but it changes the total number of questions answered. then when I've asked them to have another go, and do it again, this time make sure they submit - even though they have scored correctly - they have only been given half a point for their answer. How do I change this?
I use Chrome, and H5P plug in for Totara LMS.
Attached is the grade report- 6 pages
