When a non-existent column is added to "ref_ac_columns" attribute, additional white space is displayed.Issue When a non-existent column is added to the "ref_ac_columns" attribute for a reference variable, additional white space is displayed at the place where that column is added. For example: If the following is present in Variable attributes - ref_auto_completer=AJAXTableCompleter,ref_ac_columns=first_name;department;email1;manager,ref_ac_order_by=department,ref_ac_columns_search=true (email1 is an invalid/non-existent column added) The reference variable shows a blank white space like below: ReleaseAll ServiceNow Releases.CauseThis is expected behavior.The platform leaves blank space on the display value for these non-existent columns mentioned on the ref_ac_columns variable attribute. ResolutionRemove the non-existent columns on the ref_ac_columns variable attribute, then the display value of the variable is displayed as expected without any empty space.
