Under the ESS - Education screen, currently, you are allowing the ESS users to add the Discipline Description. This is resulting in the data discrepancy, as HR Managers are maintaining the master allowing the ESS user to add their own discretion is either duplicating the data or adding some junk data into the master.
Weekly when my HR manager user is validating the data, it becomes a project for her to correct the data.
Request you to change the field property from editable to view only, let the HR manager maintain the master.

I had raised this issue with support (ticket ID - #2106300060004412) but unfortunately, the response was not accepatable and now I have to create this issue as an idea.
