Not sure if this is the right format/place to post this, but why does deckbox not flag banned cards in commander (EDH)?

Example:
http://deckbox.org/sets/136290

http://www.wizards.com/Magic/TCG/Resources.aspx?x=magic/rules/100cardsingleton-commander

The deck listed is not a legal listing due to primeval titan.

I've seen the same with griselbrand, and a few others.

Just thought I'd actually inquire as to why? ^_^

Also, why do some decks show "standard" vs "nothing"?
http://deckbox.org/sets/310058 -> Example of "nothing"
http://deckbox.org/sets/299985 -> Example of "standard"

I've also noticed some standard decks flagging as extended?
