'Array' is appended to the title of returned search items

A strange issue has cropped up whereby, when using search, the returned items have 'Array' appended to the end of the title. Any idea why this may be happening? It can be attempted here: (e.g. try search for 'Hilda') http://www.hildatweedyarchive.org/archive/items

never mind, typo, apologies, please delete this thread

Happens to me all the time!
