Tax Data Default

Hello, I am trying to determine if something changed with the default for Employee Tax Data.  We are using Payroll for NA, version 9.2, PT 8.55.21, PUM 27.  We have multiple companies in our data base.  An employee has been working in one company for some time in two positions (empl rec 0 and 1).  He has now been hired at another campus in empl rec 2.  His tax withholding status that he is claiming at the first campus is a Special Withholding Status of NRA, Marital status = Single, Allowances = 1, and he's also claiming a tax treaty.
