Hi Micke,

you should check the module position used for desktop menu, if it's mapped to be shown also in responsive template you can exclude from mobile using the responsivizer modules manager, clicking on exclude from mobile.

You can also check the positions associations and if the desktop position is mapped you can delete it, for example 'menu' to 'responsivizer_menu'.

You should assign the responsive menu to position 'responsivizer_menu', the 2 menus need to have different positions to be independent in both templates.

Best regards

John
