STP2 incorrect ATO categories allocated

I've recently taken over an Accountright file which is STP2 compliant.  However, as part of preparing the 2023 finalisation, I checked the allocation of ATO categories to wage categories and they are wrong.  I.e. Overtime is allocated to ATO category "gross  payments" instead of "overtime" (this is just one of them).

If I update the payroll categories to reflect the correct ATO allocation, what impact will it have on pays that have already been processed and submitted to the ATO?

Any suggestions please.
