How to edit a sheet that has been uploaded in dashboard

I have uploaded a sheet in dashboard. It sees the sheet, but when I click on it, it just goes to a pop up screen and only allows me to download it back to my computer. When I go to zoho sheets, the spreadsheet is not there. If I upload the sheet directly to zoho sheets its fine, but this defeats the benefits of using the dashboard in the first place.
Thanks
