Cannot retrieve fulfillments of an order via API, only shows the fulfilled fulfillments

I’m trying to GET all fulfillments of an order. Example below:

When using the endpoint /admin/orders//fulfillments.json I only see the fulfilled fulfillment, not the unfulfilled. I marked the fulfilled fulfillment manually as such, for testing purposes.

How is this possible? Is it possible to get all unfulfilled fulfillments of an order?

Hello,

Unfulfilled are located at /admin/orders//fulfillment_orders.json

Cheers,

Gary
