Menu Tree submenu mixing with existing Menus

Hi,

I am using a Menu Tree for navigation.

In the last main menu item (for example, Dedicated), there are two submenus. When I click on the Dedicated menu, the submenus open, but they overlap and mix with the previously opened menus.

According to the Menu Tree’s expected functionality, when a main menu is clicked, any other open menus should be collapsed or hidden.

However, this behavior is not occurring with my current configuration.

Any idea, why it is behaving like this?

Thank you!!!
