Hello, I have installed MachForm 13 for a new client and they've been receiving submissions just fine. However, when we go to export submissions, the files are unreadable. The .xlsx files give a warning that the file format or file extension is not valid. When I open it on my computer, it's a complete mess. Is there a server setting that needs to be enabled to extract bulk data correctly? Or is the export for version 13 broken?
