Jehan:
This is normal. This submission could be either (1) in draft mode; or (2)
created by Assignment tool as dummy/placeholder object.
How many students are there in the site? If not too many, you can go to the
Assignment tool, list of submissions page, type in the student
name/id/email in the search field, and use download all to download the
submission data for those matched students.
Thanks,
- Zhen
