You might be opening too wide, or overfolding to 3bets, or just not playing correctly post flop OOP, depends on what mistakes do you make, cant really tell by your stats, but just try to play tighter from EP and maybe give someone experienced in 9max nl some of the hands for review, i could help you somewhat but im mainly HU and 6max player so it wouldnt really be as accurate as someone mainly playing 9max or tourneys
