What's Wrong?

CC is up to date, no settings configs regarding models has been made. Starting CC even shows a banner that Fable is now available. However, when trying to select Fable through /model, it is greyed out as it was a few days ago. But I tested "claude --model fable" in terminal and it started fable (changing model and trying to apply fable again fails in the same session). My teammates do not have this problem and can choose fable.

What Should Happen?

When applying /model, fable 5 should be selectable.
