I'm using multibib to have references at the end of each chapter but the numbering is wrong

Question

I am using multibib to have references at the end of each chapter but when I have the same reference in multiple chapters, the numbering in the text corresponds to the last chapter that the reference appears in.

The numbering in the reference sections are all fine and hyperref works correctly.

As an example, currently I get something like this:

Chapter 1

I cite ann [4], bob [2] and cat [3].

References for Chapter 1

1 ann 2 bob 3 cat

Chapter 2

I cite dug [4], ed [5] and ann [6].

References for Chapter 2

4 dug 5 ed 6 ann

So I should get ann turning up as ref 1 in chapter ref 3 in chapter 2.

Answer 1

The documentation of multibib lists the following limitation:

When numerical reference schemes are used and references to the same item appear in different bibliographies, the labels cannot be resolved properly. Rather, the replacement text (i.e, the number) is used which is defined in the auxiliary file read last.
