Shipping rates are taken over from SendCloud
When the SendCloud settings are on, the rates from your account are applied to your website. Starteenwinkel.nl can see those rates. If you do not want this, you can disable the SendCloud app in your shop's backend and enter orders manually.
Transfer to SendCloud button not visible
If the 'forward to SendCloud' button is not visible in the order overview you should check whether automatic forwarding is on.
Using both options is not possible. You choose either automatic transfer or manual.
