Can you change a personal payment method mid month?

An employee updated their personal payment method on the 19th June.

When the payroll was run the bank details picked up were for the old bank account that was ended on 19th June.

The payroll was run after the 19th June so not sure why the new bank account was not picked up.

Can someone please advise why the old bank account would be picked in the payroll?

Thanks

Mark
