OSCOLA book section repeats the book title in the brackets can't change style

I am using OSCOLA on endnote for the first time and with all my book sections (chapters) the book title is repeated. I delete the reference and input it again into endnote, but nothing works. I tried to change the output style as I see in the output style book title is twice, but for some reason it says the document could not be saved as the file does not exist. I am very frustrated as I need to hand an article in with this FN style soon and am almost about to go through and manually input it all, but don’t want to have to do that so any advice on both issues would be most appreciated. 

Example of repeat:

Kanayathu Koshy and others, ‘Impacts of Pollutants in the Asia-Pacific Region’ in Nick Harvey (ed), Global Change and Integrated Coastal Management: The Asia-Pacific Region (Global Change and Integrated Coastal Management: The Asia-Pacific Region Springer Science & Business Media 2007) 272.

Output style - why is it like this?: This is for the bibliography section though, not sure about the citation itself. 

Author|, ‘Title’| in Editor (ed)^(eds), Book Title|, vol Volume| (|Book Title, |Edition edn, |Publisher |Year|)
