    Repeating values like this are generally indicative of a relationship issue.

    Here the Visits table can't filter the PersonCalendar due to the direction of the relationship.

    Solutions : change the direction to 'bidirectional' between Visits and PersonCalendar . Will work but may cause relationship problems for other results

    OR

    rework the data model. This would depend upon what you are trying to report on

    OR

    use CROSSFILTER to filter the PersonCalendar for just this measure e.g.

    FiltAvailDays = CALCULATE([AvailableDays], CROSSFILTER(PersonCalendar[PersonIdDateKey], Visits[PersonIdDateKey], Both))
