Details from last data row shown in grand totals (see above). As suggested by helpdesk (ticket 00080530), I have managed to hide these unnecessary repeated text by using workaround - using a font color that is the same as the background color. This is a known limitation of the software, and it is totally UNNECESSARY to spend extra effort to hide text which should have never been there in the first place. This should be very basic and Board product team should get this fixed in future release
