My 420 task - Open Baby Jack Coffer 5 times, is marked as checked before I got to it.

So probably it counts the previous times that you've opened a baby jack coffer. So if you'd opened a baby jack coffer 5 times before reaching this task, you'll pass it automatically without needing to open 5 more coffers.
