Just downloaded 18.5.43 and the link on the reports page for the GST calculation worksheet takes you to Tax Summary instead.
Actually, while the list of previously created reports is labelled as Tax Summary, the reports themselves are the GST worksheet.
Not sure I understand this issue. Where is the bug? Can someone demonstrate with the screenshot?
When you click of the GST Calculation Tab on the reports page the heading of the page now shows Tax Summary.
The latest version (19.5.44) is fixing this issue.
