Amount spent and cash back

Hey guys, I’m having trouble understanding something. I invested roughly 100 AUD into ai.marketing 2 days ago to test the water, and so far it seems pretty legit. But when I look at my stats it’s saying the amount spent is $15.52, the cash back is $14.47 and that the profit is +13.16% the maths just doesn’t seem to add up. How can it say I’ve made profit if the cash back amount is less than that spent? I’m sure I’m just missing some piece of important information or something like that, but in saying that, I would like to gain some more knowledge on this whole investment strategy. Thanks in advance to any answers to my question 🤙🏽
