Oh $#!7...
I remember coming back to an older version because I didn't like some parts of newer ones, and I stayed like this since.
I am up to date now (v1.3.3087) and I saw the difference.
There are still many errors, wouldn't it be easier to centralise this data on a subpage of the template, so each individual article wouldn't have to be modified if important changes like these are made in the future versions?
I guess that this wiki is using lua for things like this, so my knowledge in this area isn't good enough to help you with that.
Luckily I could use AutoWikiBrowser (it seems that anyone is even allowed to use auto bot mode), so I corrected my mistakes, and also the other ones.
Here's the pages I edited (with a + in front of the line, first set of asterisks is after my first eroneous edits, second is v1.3.3087):
