Bank Account actually changing to ****XXXX - not just displaying that way

Client on 2019.2 has an issue with the bank account number in Bank Code Maintenance actually changing to *****XXXXX, not just displaying that way because you didn't have a Role optino checked.  Thought perhaps it was related to that Role and verified that people who could access Bank Code Maintenance had the option to see PII info.  The oddest thing is that it seems to be happening as part of Period End Processing.

Anyone else see this?
