Export underlying data form a report only shows summarized data

Hello

When exporting underlying data from a report (with a date slicer on the page) and more than one table is used in the report, only the summarized data is exported. On another page, where there is no date slicer and only one table is used, the 'Export underlying data' works; the underlying table is shown..

Is the linking of the tables causing this to happen?

Thanks.
