How to view and process to close workflow error notifications?

I executed the workflow analyzer and found that there are 55,152 Error Notifications, where 55,148 (100%) are still OPEN, and 4 are closed.

How do I view them?

How do I process these to get them to be closed?

I found the document: 11i - 12 How to Purge WFERROR (System: Error) Workflow Items? (Doc ID 804622.1)

I show the below errors.

CHILD CHILD_STATUS PARENT PARENT_STATUS COUNT(*)
WFERROR CLOSED         POAPPRV OPEN          2
WFERROR OPEN         POAPPRV OPEN          6
WFERROR OPEN          NOPARENT        58,338

I executed the query to identify the item_type/item_key combinations for the POAPPRV Errors.
When I execute the query to view the item_type/item_key POAPPRV errors in detail it returns no information for any combinations.
