Nerd Font ligatures not rendering correctly

My config.yml includes:

  fontFamily: "JetBrains Mono"

And when I fc-list : family | grep JetBrains it returns an installed font, which is also active in my terminal:

But when I record and render a file, the render includes missing characters in the prompt line:

terminalizer record testDemo --config ./config.yml
terminalizer render testDemo.yml
