Statistics page not showing previous month data

[yankees123]

In the statistics section when I click on to see monthly statistics I don't see results 
from the previous month December.  I only see January and the last session.  I am using version 1.0.0beta-2.  I know it should show previous months because I used the same version with another machine and all previous months are displayed.  
Can anyone help with this problem.

Try doing a Data/Advanced/Rebuild Data and see if it shows up.

Thanks, just tried rebuilding and there still is no statistics showing up for previous months.  
Any other ideas why it's not showing up?   My airsense 10 autoset with the same sleepyhead program shows all the months statistics.

Did you look on the SD card to see if the missing dates are on the card?

Everything has been imported correctly.  Just like to be able to look at the statistics on a month to month for comparison.

Do you have the Do Not Import Older Than date set in the Preferences?

[yankees123]

Just checked and yes it is there with a date prior to when I started using the machine.  Should it also be checked?  
Any other ideas to fix this problem?
Is it because it is a vauto model?

Anyone else who has any ideas?

OK, here's a thought.  If you archived your CPAP data to your hard drive, create a new user profile and import all the data from the previous years.
