I tried to sort the new Inventory Preload on a column called foo (I think it's a remnant from working with the API) and the table disappeared. Now there is only There is no data to display. The header row disappeared as well.
All the preloads are still there, but I cannot use the Inventory Preload menu in Global Management to look anything up.
How do I fix it? I tried looking in Safari and Chrome.
When you reload the page, there is a short moment when the headers still show up. You need to be very quick to click on another column header like Serial Number. This will disable sorting by the extension attribute and the table will show again.
