Scene.Create Problems with Helper Groups and Media entities

I’m using the scene.create service to save the state of my lights prior to fire an alarm.

If I use the helper groups created with the web UI the states are not saved correctly. If I add the individual entities to the call works perfect

The other problem es Media players. Not only doesn’t restore the previously played sorce but also doesn’t restore the volume. This happens even when added individual entities to the scene.create call

Any help or work around?
