[PC] Loud and Clear won't finish

First - I have been able to use the police radio. This is not a report about being unable to use the police radio.

The quest Loud and Clear will not complete. I have all three objectives completed (all 3 have a checkmark next to them), and there are no other objectives left to do. It simply remains in my quest log as uncompleted (no checkmark next to the quest itself).

Platform: PC

Single Player.
