When i do a LISE category loop, 
{LISEarticle action="category"}

my parent category: 
[url] => http://my-website.com/article/chambre/6/11.html

my children category: 
[url] => http://my-website.com/article/meuble/6.10/11.html

When i do a LISE category loop and want only a specific category
{LISEarticle action="category" category="chambre"}

my parent category: 
[url] => http://my-website.com/article/chambre/6/11.html

my children category: 
[url] => http://my-website.com/dev/article/chambre/6.10/11.html

So the url generated by LISE for my children category is not the same...

Well, when my loop is {LISEarticle action="category"}, everything works, all
items are filtered, OK!
Well, when my loop is LISEarticle action="category" category="chambre"}, Nope!

And the most craziest thing, i get the correct category-alias -> meuble, on the
page.

I've tested all, with subcategory, exclude_category, ... but nothing worked ! 

So, i think this is a bug in the Core of LISE.
