Can you give links to these two different wikis?
Unfortunately, that not is so old that it may not tell us much. It look like several special keywords were removed back then and the note doesn't apply to the category- ones.
It does however suggest, that you should report the problem to FANDOM staff. I'm pretty confident it is a UCP bug, since you gave a link to a UCP wiki.
The UCP version of Special:Analytics looks to be incomplete and totally different from the legacy version, but either one can not really give you more than top 10s.
So, without specific page view data, I'm not sure how you can be sure the auopopulating nav menus are wrong. Only FANDOM staff can probably tell you.
If you admin any legacy wikis, I would compare them to the UCP ones (like thunderstonequest), because it could be just one of the many, many UCP bugs.
A google search of "Foxtricky wiki" brings up nothing useful unless it is really Ratismyspecies' Wiki.
The tag at the top worries me:
This article is about a system or feature that is no longer in use.
Don't get me started about the "new" VisualEditor...
LOL the old "new galleries".
Yup, looks like a UCP bug.
One of the best ways to attract users and grow a wiki is to have a nice main page.
Here are some quick tips for how to make a good main page:
Use correct spelling and grammar.
Have a good summary about what the wiki is about on the main page.
Don't leave out key info: If the wiki is fan fic, it should say so. If the wiki is encyclopedic info it should say so. If the wiki more like a personal sandbox, it should say so.
A nice header graphic related to the topic should show up near the top of the main page.
Put links to important pages on the main page.
Don't have pages that don't have any links to them from other pages.
Make or find nice graphics for main characters or objects (planes, ships, tanks, etc.) and put them with links on the main page. This is sometimes called a profile table. You will see them on most good wikis. If you have enough pages you can make a table with links to subtopics like characters, episodes, items, quests, etc.
Make and use a nice wordmark
Make and use a nice background theme image.
Start categorizing pages.
UCP broke it... it wasn't your fault. Createbox is not supported by UCP. Supposedly there is a replacement tag, but I don't know how it should be coded. I'll call on @Andrewds1021 .
I would try to clean up and finish your main page so it doesn't looks so incomplete before trying to get more help.
Looks like a UCP bug. We need to find a legacy wiki with a slideshow to compare.
Please give a link to your wiki.
Probably better to wait until the new version of the feature is implemented.
This is starting to go off topic.
They may have different staffing times for non-English tickets... not sure how you would find out what they are, though.
My point seems to be made, regardless.
