Problem with 5/10 to 10/20 transition

[Foribald]

I'm making around 3BB/100 at 5/10 then I tried playing some 10/20 and first won 5000$ to lose 6000% thats 300BB which I thought was to much. I went down to 5/10 again to fix my game. I got my VPIP up from 24-28 and sr 37-41.

Then today I tried my luck at 10/20 again and lost 1500$. What I'm I doing wrong!?

Agg factor: 3.2
SR: 42%
VPIP 28%
Folded BB to sr: 50%
Folded SB to sr: 87%
Folded BB to steal HU: 30%

Please help me out here...a
