The menu does not display all categories

[alector]

 

I would like to ask for your help regarding a problem I am facing.

Prestashop version 1.7.6.7

(Menu module Main menu v2.2.0 - by PrestaShop)

Once I have added all the categories I want to appear in my menu, some of them do not appear to visitors.

If I log in with a client account, then all categories are displayed normally.

I have not made any changes to the user groups, and also I do not want some options to be displayed only to some users but I want all the options to be visible to everyone.

What could I do to solve my problem?

Thank you
