Order status automatically switched to “completed”

Hi,

I am using the sendle plugin but I am mostly creating my labels by “fetching” orders on sendle website directly (using url: https://app.sendle.com/dashboard/woocommerce/orders).
Labels are perfectly linked to the right order, which is great, but each time I am creating a label, API automatically switch my order status to “completed”. Is there any way to desactivate this automatic switch?

Many thanks
