Navigation can not switched

[flagpiger]

When using Navigation, I created a parent menu with two sub-menus, each configured to go to a different app. However, I found that the sub-menus cannot be switched and only the configuration of the last sub-menu is displayed. It feels like there's a naming conflict as both sub-menus are displayed in the same style in the preview. Have you encountered this issue before? How can it be resolved?
