Think i may of found a leak in my game

[Doctaprofit]

after 4300 hands ( i know this is a small sample )my PT stats are as follows
VPIP 13.99
VPIFSB 22.17
Folded SB to steal 94.12
Folded BB to steal 88.89
att to steal 17.17
WSF 30
BB/100 hands is 5.05
went to SD 29.79
won at SD 60.86
PF Raise 6.3
These stats are all from 2/4.. ill be moving up soon just need to make a little bit more b4 i feel comfortable with my roll at 3/6. Anyway based on these stats i feel that my leak might be my bb and sb defense? Are these numbers horrible? What kinda hands should i be calling with from the SB and BB to say a raise from the button. Also based on my stats are there any other apparent leaks as of now?
I would describe my play style as tight aggresive but am i playing way too tight on the BB and SB? For the most part i feel like ive been correctly folding garbage from the SB and BB but i dont know if these numbers justify that.. Any advice is greatly appreciated, thank you.
