Shaves hair, won't cut paper?

So, I have a convex edge on my Para 2, and for some reason it shaves hair, but it won't cut paper cleanly, I can't even get a good slicing cut to go through sometimes when testing it on paper. I touch it up with a strop and use white compound from stropman. Any explanations?

Bur's, or a chip. Is it hanging in one spot when you go to cut the paper? If it's sharp enough to shave with thats the only logical explanation I would have. Even one small hard to see chip would be enough to not cut paper cleanly in some cases. Can you slowly run a fingernail down the blade safely to see if it hangs anywhere?

I''ve tried checking for chips and burs, smooth as glass using my nail. Not sure if what buckmaster96 said might be the problem.

I'd guess you're using too much pressure or elevating the spine as you strop. You're getting a uniform apex but its way too broad at the cutting edge.
 
Check to see if it shaves from both sides. In other words, alternate between having one side of the bevel towards the skin, and the other side. I generally check this by using my right hand holding the knife to make a shaving stroke down my left arm, and my left hand holding the knife to make a shaving stroke down my right arm. If there's a burr or wire that's folded or leaning to one side, it'll always cut/shave better when the burr/wire is leaning into the skin, and worse or not at all when it leans away from the skin. A folded burr or wire will also cut poorly in paper or other materials, if the blade is angled slightly to one side or the other. An asymmetrical bevel could also behave similarly, because the apex of the edge will be offset to one side or the other.
