I really doubt changing the adjustable setting will make a difference.

Sounds like you are lunging at the ball.

Sounds like one for a swing coach to take a quick look at as there are so many things it could be. One picture is worth 10000 words when it comes to swings. I did do the same thing with my hybrids and the answer for me was I was playing the ball too far back in my stance. I found that for me playing the ball slight forward of center (more like I would a fairway wood) but keeping my swing feel more like I was swinging an iron,  was the right combo to fix my topping the ball pronto.
