Spanish menu not showing

Hi, I have my site with a menu for spanish and english, each articule, categories and template set to each language. Language switcher set up, I follow every step from joomla's documentation. But my spanish menu is not showing when I switch to spanish. I can fix this if I transfer my items to the english menu, that makes both menus working correctly but that´s not the correct solution, I should have a menu for each language. I don't know why this is happening. Can someone help me please?

Thanks!

Hi,
have you try falang component ? It easy to use and you don't have to duplicate menus.

No haven't try it, but I will, thanks!
