Why Doesn't the Calendar Show Earlier Dates?
The date picker shown on the Charts and Records Tabs is created by finding the earliest date in your saved records. Only normal service times are considered.
Records saved under the Other service time are not included in the date range. If you enter earlier records under the Other service time, you may not be able to select them with the date picker.
Go to the Input tab. Go back to the earliest time you want to view. Select any normal service time. Save a single value of "0" under any category. The date picker will now go back to this date.
