Many apologies if this is unmannerly, but I don't know how else to request a bounty on Why isn't the 'Map Colors' fixup changing text colors? Thank you.
The snag now is that Dietrich von Seggern commented
The Profile that you have sent uses wrong input color (other than in your initial screenshot): C97 M55 Y28 K7 instead of C99 M98 Y18 K6. When I modify your profiles values it works as expected.
But I don't see and never input 'C97 M55 Y28 K7' at all! I input "C99 M98 Y18 K6" as you can see in my screenshot
