This will fix the root cause of the above issue. An important thing to note is the distinction between replacing null values with defaults and inserting default values into null values. The former is an expected and required behaviour while the latter is unwanted. This PR leaves the former intact (and there are tests that show this), while it adds tests that make sure the latter doesn't happen and fixes it.
