Hi Cecilia,
I apologize, these threads do not link to one another so if you did provide us with a screenshot of the issue in a previous thread I’m just not able to find it at the moment.
I’m thinking you may have multiple menus/menu items added either in the Appearance<<Menus section or the Crio<<Page Headers section. Check both of those sections and make sure there is no duplicate content.
Sometimes when you switch themes, install new plugins, or xml data it will add new elements like menus that come as packaged demo data. Often times these added elements will appear as just a bunch of duplicate content so I’m thinking that’s the first place you want to look.
I hope you find this helpful.
