When you create a report within the Signature CMA platform, any changes you make within the preview section will be saved as a report Template.
If a different address to the target property is displayed on a report cover page, it is likely that the address details have been edited on the cover page of a previously produced report.
To fix this, click on the 'Edit Details' button in the cover page section of the report.
Scroll down to the property address section, edit the address as required and click 'Save' at the bottom of the panel. Your report will now display the correct address.
