Scene with wemo and light only fires one of each not both

Folks,
I have created a scene:

  • name: Festbeleuchtung Alina
    entities:
    switch.alina: on
    light.domitech_smart_led_retrofit_kit_ze27eu_level_3_0: on
  • name: Alina dunkel
    entities:
    switch.alina: off
    light.domitech_smart_led_retrofit_kit_ze27eu_level_3_0: off
    When I click on of each scene in HA GUI I have to click them twice or three time so the wemo switch and the light turned on or off. How can I fix that behavior so that a scene really reacts like a scene when I click on in in the HA GUI?
