External Tool Assignments Are Auto-Grading

[Carter41]

I am testing assignments using an external tool called Noteflight and am finding that if a student submits their assignment, they are automatically getting an A (100 score). I would like the opportunity to manually grade the submission based on the quality of the student's work.

If I create a different assignment and use Online > Text as the submission type, then I am given the opportunity to manually grade the assignment as I see fit. This is the expected behavior.

I confirmed the settings for both assignments are identical aside from the submission type.

Any idea why this is happening? Attached is a screenshot of the assignment settings for the external tool assignment. Thank you!
