I am trying to change the SKU attribute label from "SKU" to "Item" on the Product Page on the storefront by adding a label to the attribute in Admin Panel by going to
Stores > Attributes > Product
selecting "SKU" attribute in the grid and adding a label under
Manage Labels > Default Store View
It seems that the attribute label for SKU which is displayed on the Product Page on the storefront will only change if I modify the Default Label in Admin Panel.
All other attributes are properly reflected on the storefront (e.g. color, size, etc).
During my investigation, I have found out that the template responsible for rendering the SKU is
module-catalog/view/frontend/templates/product/view/attribute.phtml. However, the attribute label is not translatable therefore I cannot use translations files to change the attribute label. On the other side, I understand why the attributes displayed via above template are not translatable as - I think - the attributes labels should be changed from the Admin Panel via Manage Labels facility as described above.
Is this a bug?
