I'm not able to submit my expense report because Concur is asking me to verify that certain expenses are NOT duplicates by entering in a comment saying they are not duplicates. See error messages below. How do I resolve this?

List of flagged expenses. These are NOT duplicates

Error message saying to add in a comment that these are not dupes

I entered a comment shown here, "Not a Duplicate"

Error message after saving the expense (it is still flagged and can't submit the report)
