Human Factors; Procedure
Ramp called to unlock flight will add ballast. Flight did not have 15 bags minimum to secure DG (Dangerous Goods). Unlocked flight waiting for cargo to add DG Quick Pak. Once ballast was added (by ramp) I locked the flight. DG can go thru the locks therefore I was not notified when the DG was added. At departure and ramp finals I realized ballast is loaded with 14 bags and Quick Pak but Quick Pak did not indicate as DG. Cargo Specialist [Name] confirmed DG radioactive. Invalid flight but it did not go thru ACARS as invalid all this happened with 4 minutes of from OUT.
Air Carrier Load Planner reported a communications breakdown between Load Planner and Ramp personnel resulting in aircraft departure with incorrect Hazmat documentation.
