Hello,

Not sure it's a bug. Maybe it's a bad usage behavior.
Sorry if I mistake.

Steps to reproduce the issue

1- Create a Sidebar-left ou Sidebar-right third level menu

• Backend admin panel > Menu > Manage > Create a new menu
• Backend admin panel > Menu > [New menu] > Add some menu items (Menu Item Type = single article / Select Article = One published article)

• Backend admin panel > Content > Site Modules > Create a new "Menu" module (Select Menu = Backend admin panel > Menu > [New menu] / Position = Sidebar-left/right)

2- Frontend > Go to menu level 1 / level 2 => Breadcrumb display is OK

3- Frontend > Go to menu level 1 / level 2 / Side menu => Breadcrumb does not show parent menus

Expected result

The "Frontend > Go to menu level 1 / level 2 / Side menu" breadcrumb should display "Home/[Level1 menu]/[Level2 menu]/[Side menu]
