Platform History Stats -- Keeps incrementing

History stats keeps incrementing even though the switch is off. I’ve also unplugged the switch to ensure no rouge mqtt commands are being sent.

It was working well for a long time before I upgrade to 2022.5.4 (from 2022.4.x or 2022.3.x)

- platform: history_stats
  name: Kids Water Heater on today
  entity_id: switch.sonoff_kids_water_heater
  state: "on"
  type: time
  start: "{{ now().replace(hour=0, minute=0, second=0) }}"
  end: "{{ now() }}"
