Short description of error
Just-duplicated particle systems with a unique data slot do not immediate reflect changed settings in Particle System settings unless other steps are performed. However, if the file is saved, then reopened after closing Blender, the behavior will be as expected.

Exact steps for others to reproduce the error
In the attached file:

Duplicate the "Braids" particle system in the selected and only object with the "Particle specials" menu
Press F9 and select "Duplicate Settings"
Try changing Simple Children hair radius in the duplicated particle system to a very large value => (nothing happens)
Press Tab twice to enter/exit Edit mode
The changed particle system settings will now have an effect
