Why does the Dawn Theme image-banner.liquid return 'First Image'?

[mvcheeyong]

why is the "label":"t:section.image-banner.settings.image.label" in

"settings": [

{

"type": "image_picker",

"id": "image",

"label": "t:sections.image-banner.settings.image.label"

},

returns "First Image"

[ThomasBorowski]

t:section.image-banner.settings.image.label

references the string at that path in locales/en.default.schema.json.
