Quick translation question

There's an error on this line?

https://github.com/plone/plone.app.querystring/blob/master/plone/app/querystring/profiles/default/registry.xml#L281

    <records interface="plone.app.querystring.interfaces.IQueryField"
             prefix="plone.app.querystring.field.effectiveRange">
        <value key="title" i18n:translate="">Effective range</value>
        <value key="description" i18n:translate="">Querying this is
undefined</value>

The description seems nonsense to me.
