Deleting A Comment On The Proof DOES NOT Delete It From Workfront

When you make a comment on a proof and save it, then later go back and delete it, that comment is not longer visible in the proofing tool...... HOWEVER, In Workfront, on the project, the system created a "Proof comment: Blah, blah, blah..." on the details tab of that document that still shows the comment even after it has been deleted from the proofing tool. This is very confusing to designers looking for feedback. If the comment is deleted on the proof, the system should also delete the post in the job with the comment as well.
