#23604 delivery trying to add address but not accepting original edit code

I’m trying to add a single address and it’s not accepting the original edit code, is it supposed to be a new code?
Just one more address 0x99cEB19CfA09F46D7261B4dFD5409CA8A2538899

Hi 0xAnimal,

Due to how delivery works, it is not possible to change the address. You can however create a new delivery with only the new addresses. Use the same event ID as the previous one.
