a format specification for argument 2, as in ‘msgstr[0]’, doesn’t exist in ‘msgid_plural’

I have the following code:

public function bulk_updated_messages ( $bulk_messages = array(), $bulk_counts = array() ) {

    $bulk_messages[ $this->post_type ] = array(
        'updated'   => sprintf( _n( '%1$s %2$s updated.', '%1$s %3$s updated.', $bulk_counts['updated'], 'yosilose' ), $bulk_counts['updated'], $this->single, $this->plural ),
        'locked'    => sprintf( _n( '%1$s %2$s not updated, somebody is editing it.', '%1$s %3$s not updated, somebody is editing them.', $bulk_counts['locked'], 'yosilose' ), $bulk_counts['locked'], $this->single, $this->plural ),
        'deleted'   => sprintf( _n( '%1$s %2$s permanently deleted.', '%1$s %3$s permanently deleted.', $bulk_counts['deleted'], 'yosilose' ), $bulk_counts['deleted'], $this->single, $this->plural ),
        'trashed'   => sprintf( _n( '%1$s %2$s moved to the Trash.', '%1$s %3$s moved to the Trash.', $bulk_counts['trashed'], 'yosilose' ), $bulk_counts['trashed'], $this->single, $this->plural ),
        'untrashed' => sprintf( _n( '%1$s %2$s restored from the Trash.', '%1$s %3$s restored from the Trash.', $bulk_counts['untrashed'], 'yosilose' ), $bulk_counts['untrashed'], $this->single, $this->plural ),
    );

    return $bulk_messages;
}

And then in my .po file I have:

#, php-format
msgid "%1$s %2$s updated."
msgid_plural "%1$s %3$s updated."
msgstr[0] "%1$s %2$s actualizado/a."
msgstr[1] "%1$s %3$s actualizados/as."

But when I try to create my .mo file with Poedit, I get this error:

a format specification for argument 2, as in 'msgstr[0]', doesn't exist in 'msgid_plural'

I don’t get what’s wrong here. Is it the way I call “_n”, or something in my translated string?

I see that is somehow related to the sprintf position markers… that poedit apparently doesn’t like that I have $3%s in msgid_plurals and not in msgid… but shouldn’t just translate the string “as is”? I’ll pass the translated strings to sprintf at runtime, inserting the appropriate nouns in place…
