Missing Location in photosteam from iphone 5 to ipad 2

I toke some photos by iPhone 5, but can't found the location @photosteam in my ipad 2. In the same case, if iPhone 4 or 3gs told toke the photos, my iPad 2 can show the location in photosteam.

P.s. I can saw the location in my iMac's iPhoto ( iPhone 5, 4, 3Gs)
