Parsed RecurrenceProperties differs from its previously string-generated version

Hello,

I am trying out the Calendar and it has been awesome so far. However, I am facing this issue: I am allowing the user to create recurrence rules and everything works great, except, for example, with events that happen every 2 days with no end date. If I create the following recurrence and generate it as a recurrence rule, the calendar correctly displays the event every two days:

     RecurrenceProperties props = RecurrenceProperties(
      interval: 2,
      recurrenceType: RecurrenceType.daily,
      recurrenceRange: RecurrenceRange.noEndDate,
    );
    var startDate = DateTime.now();
    String rule = SfCalendar.generateRRule(props, startDate, startDate.add(const Duration(hours: 1)));
    // rule is 'FREQ=DAILY;INTERVAL=2'

Then, if I try to parse the rule to update its corresponding RecurrenceProperties, I end up with the following:

RecurrenceProperties parsed = SfCalendar.parseRRule(rule, startDate);
// parsed has interval: 1.

If I try to generate the rule out of parsed, I get 'FREQ=DAILY;INTERVAL=1' (interval is different). Any ideas what I could be missing here?
