The good news is that your ads will not be served like this, don't worry. This is the default preview for Dynamic Ads and this looks exactly the same when you create your campaign using Facebook's "Ads Manager". For our clients to see real previews with their images & texts, we send Facebook a product set while generating the preview but Facebook does not always provide a preview from this product set in real-time. Thus, you may see the default preview then. It is usually a temporary issue.
