citation style seems to be 'bugged'

hcaroe

Hello there,

I hope you can help. I am trying to create a particular style. I used 'search by example' and the closest style seemed to be 'The Open University - A251 - Arts course'.

I updated this style using the code editor, until it reached my specifications (my code is copied below). When I updated the style in my document, however, there is a problem with apparently random letters appearing after the date in some bibliography entries,

e.g. Wilson, C. A. (1991ag) Food and drink in Britain: from the Stone Age to recent times, (London: Constable).

In-text citations which refer to these references also do not work, and leave out the author/date, just including the page number e.g. (, 231)

I thought this must have been caused by a mistake in my coding, but when I changed style to match the unmodified version of 'The Open Univeristy - A251 - Arts course' these extra letters/this bug seemed to persist...

would be grateful for any assistance!

here is my code:

<?xml version="1.0" encoding="utf-8"?>
<style xmlns="http://purl.org/net/xbiblio/csl"; class="in-text" version="1.0" demote-non-dropping-particle="sort-only" default-locale="en-GB">
