Null values for values / fields

API Issues
1

The value null can appear in field values - both simple values, arrays and sub-objects. This has been noted before specifically for dates and addresses but I’ve come across a few more in various other fields. Examples (from a fairly old data entry) clipped for clarity - these appear fine when viewed at beta.companieshouse.
