Look fine, many armors won't accommodate this but screen references show 1 large tab and 4 1/2 to 5 small tabs, my ATA only accommodates 2 1/2 tabs, there is no requirement. When adding glue I places chest/back strapped over a box and align the fronts so the rear covers the backplate.
Also not a requirement but you can cut off (or in half) the big tab on the rear, screen suits didn't have them
From the DO's guide:
"NOTE: As seen in the photos below, there are no large tabs on the rear of the shoulder bridges. This is not specifically mentioned in the CRL, but removing them is highly recommended if possible."
Also
"Level 3, they shall free float in the back, be glued in the front and need to be held down in the back via a white elastic band to the white fabric/elastic chest/back connection."
