you might have just started to reshape the edge and after a while you'll be sharpening it.
idk though.
I think you may have too much cushion and are rounding over the edge like said before, just use something with less cushion.
and keep trying, don't stop now.

but I would start practicing with cheaper knives.
I'm only fifteen, I didn't know a whole lot about this technique when I first started, so I started with a cheap gerber I had and after a long time I got better.
keep trying and poracticing until you find what you were doing wrong, and take the all the advise the guys here give you. and try it all until you understand what you did wrong.

you'll get it.
