When opening a service call from the Additional Services window in the sales order, Ship To or Bill To address appear empty in the Address Component window.
Reproducing the issue
1. Create a sales order.
2. Open the newly created sales order and via right-click choose New Additional Services.
3. Add the new service call.
4. Back in the sales order, go to the Additional Services tab and use the yellow arrow to open the new service call.
5. Go to the Business Partner tab and use the button "..." either open the ship to or bill to Address Component window.
