I figured out that clicking on “Export” to export some display mode will not include its original name in the dialog box, hence I’m forced to remember the name and write it manually. In Rhino 7 the exported display modes had their name included in the dialog box.
Here is a direct comparison between Rhino 7 an Rhino 9 WIP:
Another bug is that when I copy an existing display mode and change its environment map, it no longer can be read by the latest WIP, hence there is no material shown in the viewport and the geometry is rendered as a blank white.

Bug number 3 is that I can’t import the same display mode made in Rhino 9 WIP into Rhino 7.
