Hi @degrusonm,
In Canvas, when you create a group assignment, the system is setup to treat it as a collaborative assignment, meaning the group members are all going to work together on one submission. When any single group member makes a submission, the submission will show as being for everyone in the group. You can choose to grade individually, but that just means you can enter a different score for student 1 and student 2, but for the same submission. The How do I assign an assignment to a course group? - Instructure Community - 633 guide goes in to a but more detail on this.
From your question, it sounds like you don't want to configure the assignment as a group assignment in Canvas. You could still have the students work together in reality, but have their work all be separate and individually submitted and graded.
Hope this helps!
