Thank you for the provided picture.
I tested the described scenario in the Bing and OpenStreetMap Providers example from our demos, however the layer is changed accordingly from the UI. I am attaching a video demonstrating my test (you can drag&drop the video in Internet Explorer in order to watch it). Can you check out the mentioned example and see how it differs from the setup on your end?
Should you need any further assistance, I would ask you to isolate the scenario in a sample project and send it over in a new support ticket (since projects cannot be added to forum posts).
