Processing cash payments is primarily intended for the organization's own insight. In this case, you can ignore the notification that too much has been paid. You can even decide that you will not process any payments at all in Athletics.app for athletes who register later.
If you do want to process all cash payments in Athletics.app and ensure that the correct amount is shown, you can do the following:
Just before the start of late registrations, change all registration fees for all categories and events. Set the fees to the amounts that will apply from that moment on.
Let's say it first costs 3 euros to register for an event during the pre-registration period. And during the post-registration period it costs 4 euros. Then you change the rates from 3 to 4 euros. Everyone who has already registered and paid in full will remain at the '3 euro rate'. New registrations must pay the '4 euro rate'. This way you avoid the notification that someone has overpaid if you enter 4 euros for a late registrant.
