Unknown Series 17 Profiles and Icons?

So i just logged on and apparently i've recieved a couple of new profiles and Icons in my collection that claims to be from the current Series 17 event however I don't see how or where they've come from?

one of the icons for example is called Gorenucopia and a profile called Harvester. Both of which say they're from Series 17 but i don't see how ? Anyone know ?
