whe you hit LOV for 'Value Set' field, if your desired value set in not being displayed, then check the 'Maximum Size' of value set. It is more than 30 for Independent value sets or 80 for Table based value sets then that value set will not be displayed in LOV. it is because of LOV query. The LOV query is given below

SELECT   flex_value_set_name, vt.meaning validation_type_meaning,
         ft.meaning format_type_meaning, v.description, v.flex_value_set_id
