The Definitive Guide to Data Quality
Reopening the job didn't solve it. I was able to remove them but only if I dragged them outside of the shaded area. I have version 5.2 for the mac. Personally I think it is a bug. If you click on it and then say delete the expected behavior is that it would delete. But on a mac you have to drag it outside the shaded job area in order to delete it. Thank you for checking up on me. I think I am fine with the way it is working.
