I'm not sure where you read that the start date cannot be changed. But, the good news is that you CAN change it! Here's how:
When you go to your report and click on the Change Start Date, you can use the arrows to move backwards or forwards through the months as needed. When you get to the month you want, you have to click on a date within that month for when you want the report to start -- I think this is the part that some members forget to do -- if you don't click on a date, then the report dates will not change. Now click on the Close button (on the calendar window). Change the end date through the same process if needed, then click on Run Report.
If you do the above and your selected start date is not used, you may want to try using a different browser.
I hope this helps!
