Ideally yo should set the AO at the highest setting & it should then be good for all lower settings at the same distance.
If you set it at lower power you might just be seeing the increase in magnification making it go "soft".
Its beginning to sound like there is something other than the scale being off happening here.
Try this & see what happens.

Rest the rifle so it can stay in place without holding.
Set the highest power for magnification.
Put a plain sheet of white paper in front of the front lens to reflect light into the scope. (usually a 45 degree angle works best.)
Briefly look into the scope & see if the reticule is immediately sharp.
If it isn't adjust the eyepiece focus until it looks sharp & then look away for a few seconds.
Go back to a quick look.
Repeat the quick look~adjust~look away~look back until it snaps into clear sharp focus when you first look in the eyepiece.
Remove the paper reflector.
Set a target up at a known distance. Visually focus the front eyepiece in the same look in~look away technique as you used before for the eyepiece.
Now slightly bob your eye up & down (or left right, either works) till the reticule doesn't "track" (move) in relation to the target.
Reduce the power setting.
do the eye bob again.

If the parallax changes as the power is reduced then there is something wrong in addition to the AO scale.
