Unable to skip schedule in case of sub-schedules

[nos86]

Hello,
first of all, thank you for your amazing work. I really like this software and the potentiality behind.

I saw that in the following configuration, Schedy is not doing the right stuff:

      schedule:
        - name: Wake-up
          rules:
            - x: "20 if state('sensor.climate_profile') != 'Holiday' else Next()"
              rules:
                - {v: 21, start: "05:30", end: "06:30"}
                - {v: 22, start: "06:30", end: "08:00"}
            - x: "22 if state('sensor.climate_profile') == 'Holiday' else Next()"
              start: "09:00"
              end: "11:00"

I expect that when it's "Holiday" the first rule (and it's sub-rules) is skipped. Instead it is processed and the temperature is assigned. The problem can be solved if I decide to avoid to write sub-rules and I repeat the rule twice: but I love the DRY approach.

Have you seen this problem?
I'm doing wrongly something?

thanks in advance,
Salvo
