Hiya @TKW199617! The only requirement for the Jack of all Trades achievement is winning a round with every original operator in ranked. If that has been done and the trophy isn't unlocked, you could try manually syncing your trophies with PSN to see if that helps at all. If syncing your trophies doesn't fix this issue, you can also complete the steps in this FAQ article for good measure. Let me know either way and I'll be happy to assist you further as needed.
