Manual order not avalaible ?

Hello, I have a trouble to create purchases manually. When I want to select a customer from the list, I can not, only the choice “guest” is offered me. How can I create an order by selecting a customer who is already registered? Before I could, but now since the update there are more this feature. Thank you in advance!
