Zanata https://translate.zanata.org/zanata/iteration/view/subscription-manager/1.1.X

"Last-Translator: nnakakit <nnakakit@fedoraproject.org>\n"
Nakakita, can you please fix Zanata for the subscription-manager/1.1.X translation of msgid "Configure Pro_xy"

Yes, I have changed from "Pro_xy の設定 (_X)" to "Proxy の設定 (_X)" for subscription-manager 1.1.X.

This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.
