Why are order numbers increasing but sales not reflecting?

[Zuschlafen]

Hello Shopify Community,

Order numbers increase but no sales, what would be the reason ? i had already couple of sales (just PayPal so far).. it means system works normally. (i have also other payments methods, like visa, master card, klarna etc, all seems active) 

Thanks in advance for your ideas and solutions.
