User noticed that some reports do not show the correct amounts and are off by some value.
This can happen if you have used date filters on the reports. CORE only shows the data from the date range specified in the filters and the reports appear to skip some data. So you should either clear the date filters or specify a range that is more appropriate in your case (say As of Today, This Year to Date, etc.). Check CORE Help Center for details on customizing and running reports.
