Im creating a category menu, but the menu is not update.

I have other post but not appear in the menu.

look:

I see all your categories under the category menu - they all happen to be sub categories, so only the main category shows in the menu bar, but if you look at it, it has sub menus for all the others.

if you want the categories like 'Talleres' to show, then it can not be a sub category of 'Presupuesto'
