Unable to update the values and delete the record for Education data under skills and qualification

The Education data record under Skills and qualifications that has been imported through LinkedIn (with source as LinkedIn) is not being deleted on performing delete action through UI. When the delete action is performed, the education section refreshes and data reappears. On editing the record to update any values and clicking save, the education section refreshes and does not save the newly added data.

While the education data record added manually through UI (with source as Talent Profile) is being deleted after performing the delete action through UI. In addition, any update in the values to the existing record, the values are updated successfully and saved.
