"In Stock" read from language files

Why the "In stock" text comes from the language files, instead of the stock localisations, as for the "Out of stock" and others? Actually, there is a "In Stock" defined by default when OpenCart is installed and it's never used.

Maybe the setting of the "default status for out of stock" (that simpy pre-selects the desired option when filling the form to insert a new product in the store - but it's still selectable there!) should be better used as a "default status for in stock".
