Steps to reproduce:

1. Make sure that you have a machine with multiple GPUs
2. Create a new project, or open an existing one
3. Make sure that Progressive GPU is set as the lightmapping backend
4. Bake the lighting
5. Notice, that GPU Baking Device under the Workflow Settings header does not match the actual baking device

Notes:

- If this issue does not reproduce, try plugging the monitor into a different GPU
- Sometimes, even after selecting the correct GPU baking device manually and restarting the editor, does not fix the issue
- Could be caused by driver updates
