Hello,
1. Currently you cannot easily remove these but I’ve added an issue to disable these if they are disabled on the form.
2. You can edit the template to remove the shipping from the commission breakdownas from the following template: templates/dashboard/reports/overview.php please see our KB article on overriding templates.
