Babies release date

I was checking to see what new DVD’s were released this week and I saw that every place* is listing the documentary Babies as being released on September 28.

Which is weird because Babies was released several weeks ago - I’ve seen it in stores. Is this a special edition or something?

*By every place, I actually mean three places. But those three are all giving the same date.

Not sure but Amazon lists it as releasing on 28 SEP and that is when Netflix first offered it.
