Scene clone bug (no devices copied)?

Scene clone bug?

I created a scene, added devices, captured values. Worked fine. Then I cloned the scene, the titled is amended with "copy", but when I open the scene there are no devices.

I can "re-capture scene" and the values for the devices in the original scene are indeed recaptured; however, there are still no devices shown in the 3 dropdown lists after the re-capture. Even if I save, close, and reopen, there are no devices shown as related to the scene.

I am assuming this is a bug as otherwise what's the benefit of the clone feature other than a roundabout way to create a scene with a new name that can never have the devices changed/edited?
