Plugin Reportit

[asterixlinux]

HI all,
I am using ReportIt and in Report Configuration --> General tab -> Reporting Period i want to have a report of last year: from February 2015 to February 2016
BUT ......... this creates only the last five months report !!!
from August 2015 to February 2016 !!!!!
I was expecting a report from February 2015 until February 2016
and NOT from August 2015 until today , February 2016 .......
WHY ?!?!?!
How is it possible ?? some idea ??
see images ...

thanks a lot
