Submenu in Sidebar produces incorrect links

Hi there!

I’m trying to add a “sub-menu” to the secondary sidebar. For this I created a new menu (via Designs -> Menus). I also created a flexible widget and changed this to contain the menu. This works fine and the submenu ist displayed. Unfortunately the generated linking are not correct. Something like this is produced:

<div class=" role="navigation" itemscope itemtype="http://schema.org/SiteNavigationElement"menu-submenu_leistungen-container" role="navigation" itemscope itemtype="http://schema.org/SiteNavigationElement">
<ul id=" role="navigation" itemscope itemtype="http://schema.org/SiteNavigationElement"menu-submenu_leistungen" role="navigation" itemscope itemtype="http://schema.org/SiteNavigationElement" class=" role="navigation" itemscope itemtype="http://schema.org/SiteNavigationElement"menu" role="navigation" itemscope itemtype="http://schema.org/SiteNavigationElement">
<li id=" role="navigation" itemscope itemtype="http://schema.org/SiteNavigationElement"menu-item-43" role="navigation" itemscope itemtype="http://schema.org/SiteNavigationElement" class=" role="navigation" itemscope itemtype="http://schema.org/SiteNavigationElement"menu-item menu-item-type-post_type menu-item-object-page current-menu-item page_item page-item-28 current_page_item menu-item-43 active" role="navigation" itemscope itemtype="http://schema.org/SiteNavigationElement"><a href=" role="navigation" itemscope itemtype="http://schema.org/SiteNavigationElement"http://sd.abozilla.de/leistungen/schluesseldienst/" role="navigation" itemscope itemtype="http://schema.org/SiteNavigationElement" itemprop=" role="navigation" itemscope itemtype="http://schema.org/SiteNavigationElement"url" role="navigation" itemscope itemtype="http://schema.org/SiteNavigationElement">Schlüsseldienst</a></li>

As you can see there is some stuff like ” role=”navigation” itemscope itemtype=”http://schema.org/SiteN….” added. This seems to come from the function enlightenment_nav_menu_container_extra_atts( $nav_menu, $args ) in ./core/navigation.php (line 26). If I change the $atts-variable to “” the generated code works, but of course lacks the extra data.

The linking in the main-navigation works fine in every situation so I guess the is some filtering missing if the “menu” is the main-menu or a submenu.

Any ideas how to fix this correctly?

Best regards
