This field is problematic, to the extent of being unusable.
- If you make it non-required, and users just accept the displayed order, then it submits blank. This is a problem if you use the shuffle option.
- If you make it required, and users accept the displayed order, then it is very unclear what the user has to do. They need to basically move something, then move it back.
I would suggest there needs to be either a panel where you add things in the correct order, or there needs to be a "accept this order" or "Done" button.
