Can’t get 2 menus in a sidebar

Hi again

I created a sidebar for Services.
This sidebar contains 2 custom menus, in order to separate services in two categories.

Sidebar
– Menu 1
—- Service 1
—- Service 2
– Menu 2
—- Service 3
—- Service 4

It show up the 3 menus but theyr don’t have the same look&feel

In source code, the first seems to have the class=”menu side_bar_menu” fr the ul
The second has only the “menu”

Thanks
