still not working

Hello Gabriel,
This is not a problem actually. The display options menu has changed since the last update. If you want to hide a specific element on your page, change to the screen size you want to hide it and select Display: Hidden.

ok, but how can I know the effect on each option other than hidden?
thanks!
