In some cases the output in our interface shows account number as XXXX9999 not the correct 99999999

While created a CHANGES ONLY, HCM extract am using :
UE - PERSONAL_PAYMENTS_RANGE; DBI - Clear Bank Account Number

to get Bank account details of an employee (new / updated).
Clear Bank Account Number - should return all the 8 digits of UK Bank Account Number, example - 12345678.
On some environments, its returning full - while on some its returning masked bank account number, example - XXXX5678 (i.e. the first 4 digits masked).

Extract output requires full bank account details.

Please suggest where am I going wrong or some other DBI to use or is it some role / privilege issue?
