The list template of a child field under "Show parents" shows some fields of the parent record. When you click on a filtered link it will direct you to the parent list, without applying the proper filter.
When editing the filter link :
index.php?option=com_cobalt&task=records.filter&filter_name[0]=filter_2&filter_val[0]=129000B§ion_id=1&view_what=show_parents&Itemid=137
and removing the &view_what=show parents
it will produce the correct result.
