Lybunt incorrect / misleading rowCount information
The Lybunt report declares a misleading number of rows because it includes the rollup row in the count.
So for example there are 9 matching contacts but we see the confusing message Rows Listed 9, Rows found 10. The 10th Row is a calculation of the total rows.
When there is just one screen we can remove a row that is meant to help - but doesn't & the 'Total Rows' line goes away.
However, when there are multiple pages we have both the pager & the totals to deal with. If we remove the row from the totals count but not the pager it creates a confusing mismatch. If we remove from both the last row may become unreachable.
On the Lybunt report a maximum of one level of group by is in play. However, where reports support multiple levels of group by it's unknowable how many rows are rollup rows.
This might all be an argument against the use of Rollup - but not going there at this stage I think my best proposal is to add text to indicate the possible presence of calc rows in the Total Rows
