Admin Menu items duplicates under Components Menu after 4.2.2 upgrade

-- HikaShop version -- : 4.2.2
-- Joomla version -- : 3.9.13
-- PHP version -- : 7.1.14
-- Browser(s) name and version -- : Firefox 70.0.1
-- Error-message(debug-mod must be tuned on) -- : none

Upon upgrading to the latest 4.2.2, I noticed all the Hikashop Component Menu items nested under Hikashop had been duplicated under the main Components menu (see attached underlined in red).

Is this an expected behaviour?

Hi,

No. This indicates that you have data integrity issues with the backend menu items in the database.
You would have to delete the unecessary menu items in the "menus" table of your database via your phpmyadmin and then click on the "rebuild" button of the Joomla menu manager in order to try to fix the situation for the next time you update.

Thanks for the pointer.
