Data does not populate after date change
I am creating a copy of a report that has been used in the past for a client. The only item changing on the graphs, is the date range (May 2016 - May 2017). When I change the date range, there is no information shown for the most recent months. If go back further (Feb 2016 - Feb 2017) all of the data is shown. The data source says it is working. I am not sure why the report will not pull in the new date range.
Does anyone have an idea of what I did/am doing wrong?
