Not sure if this is bracer specific or all new BoA items, but note the bracers on this particular character:
http://us.battle.net/d3/en/profile/Heely-1591/hero/1331800
Have +207 Strength, but if you view this item in the API:

The Strength does not appear.
Hope this helps narrow down the bug, I'm sure I'll get more reports of more characters with this issue over the next day. If you'd like more examples, I'll be sure to provide.
