AutoStakkert! 3.1.4 (x64) undesired effect caused by inadvertently pressing CTRL + V which turns on "Column Noise Correction (vertical lines)"

I inadvertently made a mistake in AutoStakkert!3 - I pressed CTRL + V (intending to paste something into a different app) and it didn't seem to do anything (but it toggles a sub menu selection) then output frames sky (and Jupiter but not as noticeable) has more brightness or lower contrast on the left and right end of the image and darker or higher contrast in the middle. For me it causes an "optical illusion" that Jupiter is stretched, or has a very flat top and bottom..
