color swatches disable atribute style blured crux don’t show

I’m glad to write you, i know i’m a free user, but in this momment i can’t afford the initial payment, but i’m trying to do my best to make my store to sell more so i can pay for the pro version, so the problem is that even if I choose the option in the disable atribute style for my color swatches , I mean i want that the people see an atribute marked with an crux when is off stock, but right now i don’t know why that is not working, hope you can help me.

Blessings
