Lightroom: Copy paste selective settings copies unselected settings
In Lightroom Mobile CC (At least on iPad and mobile (IOS) ) If you for example copy just the tone curve in "copy settings" and then you paste the settings to another picture it also copy/paste other settings. For example the "Color" settings. Even though you did not choose to copy the color settings. This was also confirmed with your support that recommended me to report the bug here too.
