Setting an order when logged out only a registration form is shown

-- url of the page with the problem -- : www.scramble.nl
-- HikaShop version -- : 5.1.0
-- Joomla version -- : 5.1.4
-- PHP version -- : 8.1
-- Browser(s) name and version -- : Edge 128.0.2739.42

When you set an order in the shop without being logged in into Joomla the login view of the workflow only shows a registration form. But the user might already have an account and should also be able to just log in at that time.
Second question affiliated with this. Can you allow a guest check out (without creating an account)?

I just found it 2 minutes after posting. So this one is solved already.
