Sounds like the bevel is not set 100%,
it make take some gymnastics to get it there.
Give a bit more description,
Is the entire edge less than perfect?
Or is it spotty for lack of a better term (sharp some places but not everywhere)?
Which tests are you using to verify the bevel is set?

Going up the ladder prior to the blade being ready is an exercise in futility (ask me how I know...)
Let us know and we will see if we can get you straightened out.
