Attachment doesn't work with advanced sef

[bettinz]

Hello, I've a problem:

I've a category called news and a subcategory called breaking news.
I also have a menu item called news that show all news from subcategories (like breaking news).

With Advanced SEF and this settings:
URL Prefix for Category: none
use ID for article: no
use alias for article: yes
use category id: no
use category alias: yes

It works
But, If I set "URL Prefix for Category" to "article category", attachments return error 404
without advanced sef:
www.domain.tld/news/item/{id}-title.html
www.domain.tld/news/download/*hash*.html <- it works

with advanced sef but without category prefix
www.domain.tld/news/{id}-title.html
www.domain.tld/news/download/*hash*.html <- it works

with advanced sef and category prefix
www.domain.tld/news/sport/{id}-title.html
www.domain.tld/news/download/*hash*.html <- it doesn't work

if I manually wrote
http://www.domain.tld/news/sport/download/*hash*.html <- it works

Am I doing something wrong?

Thank you
