Yandex Metrica Vs Ga Traffic Very Different?

I have the GA add on with the UA code copied in there. I also have the Yandex Code as an HTML block with Smarty Support (with "literal") on the default tab on layouts.

Could anyone explain why my GA numbers are 20/30 per day but my Yandex numbers are 300ish? I thought GA would refer to it as referral traffic - very confused at to why this is happening. Any help much appreciates:
