Translation (editorial): FAQ: Can I go back to using the original keywords again?

The name of button on "revert keywords" page has been changed. Please modify the translation for the following sentence:

<English>
The user can click the Revert Back to System Default for each Business Activity.

<Current Japanese>
ユーザーはビジネスサブカテゴリごとに「システム既定値に戻す」をクリックできます。

<Suggested Japanese>
「システム既定値に戻す」→「既定に戻す」

Note: The original English says "Revert Back to System Default" but name of the actual button is just "Revert." Please modify the English first if it is necessary, but make sure to ask the translators to use the above translation for the button.
