In MCC, I can no longer add new boot options

I'm not sure when this changed, but I discovered recently that my MCC boot loader setup changed.
I used to be able to reorder the boot options or add new ones (like one for Windows, which I seldom boot into).
Now, MCC->Boot->Set up boot loader->Next looks like the attached image.
What's going on?
