The DPS you see at the top (big one) is a combined DPS of both Damager Over Time and Damage. In the update notes I specified that I've moved every single type of tracker out into it's own so I could maintain a better set of stats and also added in combined views in the settings.
So what you would want to enabled for basic display settings is Combined Total Overall Damage and Combined DPS. You'll notice the two DPS are are different
Because of this large change as well it would have been horrible of me to delete everyones custom settings and just impose my own; so I just put it in the update notes/reddit/google+ post about it ^^
