Accrual balance reduces by 22 days if leave is applied from Chinese language

Content

Hello exports,

 I am facing a strange error in absence management, when an employee applies leave in English the balance reduces based on number of days, but if an employee applies in Chinese (Traditional or Simplified) the balance by default reduces by 22 days. To identify if the issue is with formula, i hard coded the formula, it was working fine. Oracle support confirmed instead of using (Person_type='Employee') in FF, Provide the Chinese conversion to make the system understand. Accordingly i used (Person_type='Employee' or Person_type='雇员'). Still i am facing the same issue. I am attaching the formula with this content.
