How to correct this “Astuces” Mega Menu so that to display all his subtitles ???

Hello.

SINCE LAST FRIDAY, WE HAD CONTACTED YOU TO ASK THROUGH THIS POST (https://forum.tagdiv.com/topic/why-dont-the-subcategories-of-the-astuces-mega-menu-display-normally/) THE SAME REQUEST EXPOSED BELOW. SEEN, THAT YOU HAVE STILL NOT RESPONDED, WE DECIDE TO REITERATE THE REQUEST:

We are using “Newspaper HISTORY” Theme (https://demo.tagdiv.com/newspaper_history/).

We changed the category and the Mega-Menu “TIME PERIOD” and its sub-menu (sub-title: “Early Middle Ages”, “Early Modern”, “High Middle Ages”, “Modern”, “Prehistory”) in our WordPress Dashboard by a new category and “Astuces” menu with its submenus (“Bien-être”, “Cuisine”, “Culture”, “Nature”, “Santé”). To this, we have created a new category “Voyage” linked to the category “Astuces” as you can see in the following screenshot: https://imgur.com/a/kCW1APl.

– The first problem is that as you can see on the following screenshot: https://imgur.com/a/XFRtixQ, we do not see appearing in the list of sub-menus linked to the “Astuces” menu, the new category “Voyage” created and also linked to the “Astuces” menu. Why is that ???

– The second problem is at the level of the “Sticky” mode which appears when you scroll down, as you can see on the second following screenshot: https://imgur.com/a/MRyTXiT, on the other hand, we see display in the list of sub-menus linked to the “Astuces” menu, two other new categories including “Immobilier” and “Mode” which are not at all linked to the “Astuces” menu and oddly we do not see the “Santé” categories and yet another “Voyage” times that are normally linked to the “Astuces” menu. Why is that ???

How, then, to standardize or correct the “Astuces” Mega Menu so as to display only in subtitles, the submenus or subcategories which are linked to it ???
