Look at both sides, realize a rolling-X stroke is a mild variance of the pressure along the length of the blade.
You will have to adjust your stroke manipulating to hit all of the bevel evenly (note this does not mean the bevel will be even it may be wider/narrower in some areas).
If it is a real problem you can also use light finger pressure at the trouble spot.
From what you are explaining the bevel is not set in that area and moving up the progression will do nothing.
