Seller Amp

I am new to selling on amazon FBA. I recently shipped my first listing to amazon Fba but i am a little confused because i also use the Seller Amp tool to validate the products and make sure I'm buying a winning product. However, for some reason the Seller Amp tool shows that i made some sales that do no reflect on amazon seller central and i am just assuming is because the Seller Amp is just not accurate at all when it comes to that. I would like to know if someone has any idea why the Seller Amp shows sales that apparently never happened.
