For facility request tasks in its 'Description' field for Location information, its sys_id is getting displayed instead of the actual location.
There is a custom business rule which sets the value for the 'Description' field using values stored in 'question_answer' table. This business rule also checks for the type of the variable to decide whether to use getDisplayValue() method or not. And for 'Location' variable which is of type 'Lookup Select Box', it does not use getDisplayValue() method instead uses variable value which is the sys_id.
Review the custom business rule and change it to use 'getDisplayValue()' method for variable 'Location' which is of type 'LookupSelect Box'.
Perform this change in a lower environment first before applying it in the production.
