Is it normal to have the module name appear multiple times in my admin menu?

Several menu entries with the same name may come from module tabs created during installation or an update, but the label alone does not identify which entries are unnecessary.

Do not delete menus simply by keeping the last one. Tabs are linked to controllers, their position in the menu and employee profile permissions. A module may require several tabs.

Send support a screenshot of the menu and its submenus, the module name and version, the PrestaShop version and the actions performed before the duplicate appeared. Support or your webmaster can identify the affected tabs and check their ownership before proposing an appropriate cleanup.
