You want the De-Esser.
I have no hands-on with his. Read through the notes. There are restrictions.
I thought you sounded fine. Note once you change your correction suite, you need to stick with it through a book. ACX puts a high value on consistency.

Back to the Projects. I think it’s forbidden to Copy and Paste AUP files from anywhere to anywhere else, and it is required that each AUP file be in the same location or folder with it’s associated _DATA folder. It is absolutely forbidden to change the name of either one.
