Error when setting up a scene using shelly lights but not when using the light directly

Hi All

I am trying to setup a scene for my bedroom that turns on 3 hue lights and 2 shelly lights. At the moment only 1 of the shelly lights turns on. If I edit the scene I can see the error:

RPC call error occurred while calling action for light.shellyprodm2pm_2ca1f64c_light_0 of shellyprodm2pm-2cb1f64c

but when I turn the light on using home assistant outside of the scene the light works fine.

Can anyone explain to me why I’d be getting an error in the scene and not when “manually” turning the light on (using the HA dashboard).

Thanks
