What's Wrong?

I tried to use Sonnet 5 but it came back with an error saying not available, so I selected Sonnet 4.6 which is what is showing in the footer on my desktop window. But the system context reports "sonnet 5". My OS is Windows 11 and I am using the desktop app.

What Should Happen?

The context and display should report the same model.
