[Koha] Strange issues with items after upgrading to Koha 3

Hi, We appear to have an issue with our items table after upgrading to Koha 3. A number of books just do not appear in the items table, and as a result we can't issue them or modify the item details. We are running Marc 21 - is there a script we need to run to make this part of the import work? The Item Data appears in the Marc record in the biblioitems table.
