Breadcrumb issue?

When i am on a listing page like this:
mysite.co.uk/directory/peterborough/type/test-tax/listing/test-place/
my breadcrumb looks like this:
Home > Places > Peterborough > Test Tax > test place

Test Tax links to /directory/peterborough/type/test-tax – correct
Peterborough links to /directory/peterborough/type/test-tax – but it should link to /directory/peterborough

If i’m on the following page:
mysite.co.uk/directory/peterborough/type/test-tax
my breadcrumb looks like this:
Home > Places > Peterborough > Test Tax
and Peterborough links correctly to /directory/peterborough

Thanks
