I noticed when you are in the webbased admin console (http://localhost:7071) and click on "Global Settings" on the left panel, the menu in the right panel has: "Save" and "Download".
When you click away, say on "Admin Extensions" and click back on "Global Settings", there are 2 sets of "Save" and "Download". Clicking away and back to it a 3rd time, there are 3 sets. Again, and there are 4 sets.
4 Screenshots attached.
