Report not working correctly

Report not working correctly

I am running an Inventory Report and I am getting the same data for a 30 day, 7 day and 2 day time span on the report.  It seems the report will only show the last two says of data.  If I run a forecast report it will show data from over 7 days ago so it is being captured but I am not able to get reporting for some reason.  Any suggestions on what I may be doing wrong?
