Automatic color change not working

Hi all,

Recently, I've been facing a problem with a very simple feature in illustrator.

Just for for example: in the colour picker, if I change the shade of magenta from 60% to 70% – either scolling the colour bar or typing the number, it doesn't matter, ok? –, Illustrator doesn't apply the colour change result autommatically in the object anymore. I have to press 'Enter' every time to have the result made, which has been making me waste time while working.

Does someone know how to fix it?

Thank you

Best Regards,

Elmo Rosa
