These fields are set using IDs from the previous CORE service. There was an incorrect assumption that these fields were integers so we were casting them as such. We have discovered that these fields are strings (e.g., `027`) so this change adjusts our types.
We were previously blocking the import of locations that belonged to schemes where the end date was before the current date. This meant that we were unable to import logs that are associated with schemes that _were_ valid, but have since expired.
