If the word that this string is referring to is "Chats" (plural), we should translate "Recent" as "Recientes" (plural form), instead of "Reciente" (singular form). We already use a plural form in the Widget.Recent.Mixed string: "Ambos" (Both). On the other hand, if this solution doesn't fit, we can make an exception and leave it in singular "Reciente". It wouldn't lose the meaning.
