# Context
- https://digital.dclg.gov.uk/jira/browse/CLDC-2287
- bulk upload errors on setup fields are not being categorised as setup errors
# Changes
- ensure errors on setup field are categorised as `setup` errors
- ordering of validations tweaked, so `validate_nulls` is further down the execution order. this is so any existing validation run first and `validate_nulls` only adds errors if there aren't any existing errors on a field
- removed old 16/60% tests are no longer required due to introduction of `how to fix` journey
