Birth cert question

I am in possession of a birth cert from 1964, which has been used for all my records since then.

DEIMHNIÚ BREITHE

BIRTH CERTIFICATE

Na hAchtanna um Chlar Breitheanna agus Básanna 1863 go 1952

BIRTHS AND DEATHS REGISTRATION ACTS 1863 to 1952

I have recently accessed the birth cert now held on the system under the Civil Registration Act 2004 and there are two pieces of information held

<< This first piece is just FYI: not really an issue

1: the (digitally accessible)record, which is typed in from the original book where my father registered, has misread my mothers maiden name.

They will change it if i want but the script will be replaced with type so the digital version of the original script will be lost

[It was all written in the old Irish script].>>

2: the (digitally accessible) index, has an error in my surname and is not the same as the 1964 birth cert.

The Civil registration Office says it cannot change the index so my question is what legal redress do I have here to have the index based on the Civil Registration Act 2004 amended to reflect the 1964 birth cert.

Thanks as always
