I've been using LaTeX for quite some years now but only for engineering papers/articles. Now a friend of mine (Law major) is trying to learn how to use it but is having some trouble with their citation method. In law they apparently often use Oscola (https://www.ctan.org/pkg/oscola?lang=en) and this is what seems to be giving the problem. My references are undefined for some reason...
While creating our own documents we ran into problems but even using the example (oscola.tex) in the package example seems to give the same result. See the image below where the output (top is from my output, bottom from example pdf) is slightly different but the references (at least 1, 2 and 3) should be the same.

My output:

Another example (and proof that something fishy is going on) is here on this forum: http://tex.stackexchange.com/questions/ ... tion-style. The author says it should look like:

I tried all the usual:
1. pdflatex, bibtex, pdflatex, pdflatex
2. Deleting all build files

I'm using Texmaker 4.4.1 and MikTex 2.9.
