I am in Sales page. Add a new Product, I select one of the available products and the "Unit Price" won't automatically fill out the Unit Price of the product. The sales price is 0,00 and not the price which is set at the product. All other informations of the selected product are available (e.g. taxes).

When I look at my products, the sales prices are there. I've also tried it with several other products.
Do I lose something to set? or does the Unit Price must be manually filled by users?
