Hi there I may have found a solution to why you don't have your rank.
I just purchased [PRO] and it does not show in tab, I am guessing this is the same problem for you which is why you think you have no rank. But in reality we both have our ranks, if you look on the scoreboard you will see your name and your rank. In your case it would say Rank: NOOB.
