auto complete reference fields not working

[Community Alums]

I am trying to use the autocomplete function on the change form, CI field. I am using the following...

ref_auto_completer=AJAXTableCompleter,ref_contributions=task_show_ci_map;show_related_records,ref_ac_columns=sys_class_name;manufacturer;model_id;serial_number,ref_ac_order_by=sys_class_name,ref_ac_columns_search=true

However, I am unable to search by sys_class_name. I can type anything else in the field and it will narrow down, class name does nothing. Thoughts?

I have also tried every combination explained in the docs on auto_complete reference fields. this attribute logic seems to be working fine on fields referencing to sys_user and cmdb_ci but for some reason its not working for the reference field referencing to cmdb_ci_service. Am I missing some logic here.?
