you are direct linking to the offer in campaign settings, so every visit is going straight to the offer.
Clicks - If you had a landing page and someone had clicked through the CTR, then you would see it showing as a "Click"
Conversions - You've had 0 conversions, or your postback isnt working
On top of what nick listed already, you have cost model set to CPA, in order to see some costs, switch to CPC and set the value to what you are realistically per click.
1. make sure you have set up the traffic source tokens correctly
2. make sure you have enabled the "Track" switch next to each token: https://screencast.com/t/inMmwQEie
3. make sure you hare using the right urls when creating campaigns 
hope this'll help
You rock!
Thank you very much. 
Hi matuloo,
Just want to ask question on what cost model to select if I advertise on Facebook, PopAds and PropellerAds? Since this traffic source as using CPM.
For PopAds and PropellerAds, I believe it should be CPM. For Facebook, I don't know what to select. I don't enter the bid amount manually. I just set the daily budget to $40 and the bid amount is set to automatic.
