Date matching oddity

I'm trying to use date matching on the contents of an OCR'd PDF.
It works in some cases, but not all. The oddity is because if I go into the PDF and do a manual search for the data, it returns a match (so doesn't appear to be a problem with the OCRing. But Hazel can't see it.
I've set up the date, I think I've correctly set up the tokens in the date. Is there anything I should know about/should try to get it to match? I don't quite understand the different between some of the options with regards to the tokens (e.g for the day 31 and 31)
Any suggestions?
