"Primary shipping address" missing in .po file

"Primary shipping address" cannot be translated in "My account", because is missing in .po file
(in french and ...?)
(though "Primary billing address" is translated)

solved by creating the following .po file * with an editor :

# French translation of Commerce Kickstart (7.x-2.4)
# Copyright (c) 2013 by the French translation team
#
msgid ""
msgstr ""
"Project-Id-Version: Commerce Kickstart (7.x-2.4)\n"

msgid "Primary billing address"
msgstr "Adresse principale de facturation"
msgid "Primary shipping address"
msgstr "Adresse principale d\'expédition"

* from original .po file; that's for french translation but should be ok, adaptated to any other language
