As mentioned in another thread the KPA seams to try to normalize the level of the profiles.
At least in older firmware versions did it not work proper - in some cases it may be related to the 'return level' bug.
To compensate all this I used to change the Volume setting (Cabinet block) in some of my rigs.
I found that some of my profiles distort with the recent firmware.
For users of my profiles I have a workaround - it may be the same for profiles from other users as well - that's why I think it fits into this section.
Most distorting rigs us the 'Stereo Widener' - check 'Intensity' high levels seam to increase the overall volume!
There are two ways to fix it:
a) Reduce the 'Intensity'
b) Reduce the Volume setting in the CAB block
For distorting profiles without the 'Stereo Widener'
Reduce the Volume setting in the CAB block
