When running Sales Reports in MassageBook, you will have the ability to customize the date range for the report. If your report is displaying the wrong date range after adjusting the the "From" and "To" dates, it likely means that the adjustments were made too quickly, or that you have attempted to manually type in the date range rather than selecting from the calendar that displays upon selecting the date field.
When adjusting the date range for a Sales Report, it is required that you use the calendar option to click on the date you wish to select rather than attempting to type out the date. It is also important that you first adjust the "From" date, and then allow the page to completely load the new information before adjusting the "To" date. Once the page has fully loaded the new information, you should then be able to adjust the "To" date.
This should ensure that the report is displaying the information for your desired date range.
