DateRange and Granularity enums not working properly

[LemaMichael]

These are the following results I get for the following dateRange and granularity

1. range (DateRange.fiveDays) and granularity (Granularity.oneHour) gives price result between aug 14 - aug 27
2. range (DateRange.fiveDays) and granularity (Granularity.sixhours) gives price result between jun 12 - aug 26
3. range (DateRange.fiveDays) and granularity (Granularity.oneDay) gives price result between oct 31 2017 - aug 26
4. range (DateRange.oneQuarter) and granularity (Granularity.oneDay) gives price result between oct 31 2017 - aug 26
5. range (DateRange.threeDays) and granularity (Granularity.fifteenMinutes) gives price result between aug 23 - aug 26
6. range (DateRange.threeDays) and granularity (Granularity.onehour) gives price result between aug 14 2017 - aug 27
7. range (DateRange.oneMonth) and granularity (Granularity.sixhours) gives price result between jun 12 - aug 27
8. range (DateRange.oneMonth) and granularity (Granularity.ondeDay) gives price result between oct 31, 2017 - aug 26

None of the granularities work for the Date range of one year, three years and five years.
