Employee not able to see the comments in the confirm review meeting task by Manager

Summary:

In the confirm review meeting task firstly the line manager confirms the date of the review meeting held and enters some comments about the meeting, but later when the employee acknowledges the review meeting those comments are no longer visible not even to the HR Super user in the front end.

Our requirement is to have visibility of the comments entered by Line Manager to both HR Super user and the employee. How can we achieve that.
