Sales Order List Report - Export

I want to run a report that i can export for ALL All Sales Orders (and associated detail) within filters set but unable to see how to do? Have tried AI Assistant, App Help and Reporting but all results / summary of how to do is not accurate and does not pull up Sales Order information. 

Sales Order - says to filter as required then click ont the Export button but no Export button exists?

Reporting - states all Quotes, Sales Order & Invoice information can be filtered etc to then produce report but when open the report, there is no option to specify Sales Orders and search only returns Invoice information.

Can anyone help as i want to look at Open Sales Orders and detail within to assist with follow up
