Problema double ## in new responsive menú

Hello team!! I’ve been on vacation, apologize for the delay in response. We have solved the problem of the drop down menus with the double ##, but it generates a Java error that in the medium term will give problems. Any alternative to using # so that not the Java bug? Without having to duplicate the content in the top menu in relation to the first lower menu. Translating Google, apologies for the translation. And second question, how can we change the default colors of menus and submenus autonomously to the desktop version? It has changed all the code of customizations of the old menu that we had made in enough pages with Enfold. Thank you very much!!
