Two equal entities, one does not appear in the energy management

Hello,
I have 2 entity from a Shelly 2.5, the consumption of each channel is measured separately. I want to add it in Energy management.
I add this code in YAML configuration:

  • platform: integration
    source: sensor.shelly_salotto_2_channel_1_power
    name: shelly_salotto_2_channel_1_spesa
    unit_prefix: k
    round: 2
  • platform: integration
    source: sensor.shelly_salotto_2_channel_2_power
    name: shelly_salotto_2_channel_2_spesa
    unit_prefix: k
    round: 2

It works and records consumption but if I try to add this only first channel is avaiable in the list of entity:

How can I do to add all channel in energy monitor?

Thanks a lot.
Marco
