Greetings, sorry for bothering, I was trying to look for the source of the issue with other users as well.

I thought Template:Customers is the main reason that makes categories broken, but think it over, I don't see any problem with the template currently.

Consequently, I point towards Template:SimpleNavbox (Template:Customers is made by Template:SimpleNavbox), I have noticed that the code:  isn't completly closed, so I modify it slightly, then I make two edits as the test, the result is "none of category is removed automatically".

So I guess "SimpleNavbox" is the source of the category issue.
