Hide ToDo List option doesn't work

Hello,

Today I was editing a bit my Site settings and I noticed the option to hide my ToDo List from public and have it as private.
I tried to activate the option, then open my profile with an incognito tab and it showed the ToDo list section with the achievements.

Not only that, I tried to add some more achievements in my ToDo list and it didn't update the incognito tab UNTIL I opened my profile with the logged user (the main tab).

I think there's something wrong with the Hide option and the refreshing of settings/achievements for the ToDo list
