Issue with Advance Account field in Employee Advance [V12]

Hi ,

In the Employee Advance form, we have set the Advance Account field to be automatically fetched from a custom field in the Employee Form. This worked fine in V10 and V11 but it’s not working in V12! When an employee launches a new Employee Advance form, the Advance Account just flashes in the field for a second and disappears

We’ve tried using add_fetch as well but the result is the same. Any ideas what could be the issue?

Kind regards,
