Grand total still being doubled when 2 products are used

Grand total still being doubled when 2 products are used

In the Reports & Dashboards the Grand total is still being doubled when 2 products are used. Making them absolutely useless for statistics.

For example.

If someone sells a
'Half Page' for £3000
'Web Package" for £1000
Grand Total : 4000

It'll display like this in the Dashboard report
Half Page / Web Package (2)
                                          :£8000
