Allowed Extension in H5P upload

Hi all! I have Opigno running on a server and am currently trying to do up some demo courses. I want the user to be able to upload a picture of themselves. However, when I change the "Allowed Extensions" in the H5P upload activity, it does not update for the user when doing the course, it instead remains as the default list. Allowed types: txt doc docx xls xlsx ppt pptx pdf odt ods odp. The formats I give it (pdf png jpg gif) are still there when I go back to edit the activity too. Any help is greatly appreciated!
