Im having a strange problem with an assignment in one of our modules in moodle. We are currently running Moodle Moodle 2.8.10 (Build: 20160111) As fas as i am aware the issue i am about to describe is only happening in one assignment in one module (or subject as we call them). We are using The Assignment mod version (Standard 2014111001) There is an assignment which has been configured for file upload. out of 120 student 65 uploaded within the time limit specified. However as a teacher when you goto the assignment overview it says 15 people have uploaded.
If you view the assignment submissons you can see the 65 odd assignments upload but 15 of them have been marked as submitted for assignment the others have not and i have no idea why this is. I have attached screenshots so you can see what i mean. You can see some of the 15 submitted at the top of the first screenshot however near the bottom other students have submitted the assignment but do not show up as submitted for grading.
Any help or advise as to why this is so i can inform the teacher as to why this would be happening i would be most grateful.
