"Require comments when rejecting items" greys out if you make any changes to "Show Violations," then set back to "Do Not Show violations."
Here is the use case of the issue.
Test 1: Do not make any changes to "Show Violations …"
Checkbox is not greyed out and can be checked.
The campaign works as expected. That is, a reviewer must add a comment before rejecting any item.
Test 2: Make any changes to "Show Violations …", then set back to defaults
As test 1 shows is possible, it is often desirable to require comments for rejections, even when this is not driven by violations.
