Hello,
A bit of background for you. Reading Life originally launched on iOS, and then was rolled out to other platforms in the Kobo family.
Some of the awards are platform specific. For example, the easter egg award is iOS only, and you likely won't see it appear when synced on another platform. eReading Rainbow is an Android only award and when synced it's not seen on another platform.
You can find a list of most, if not all, of the awards and on what platform they exist here:
