Phase and cause were only coded from 2008, so earlier years show nothing while one of those filters is on.

Phase and cause come from the NTSB’s own coding of each accident, which only exists from 2008 on, so these two filters leave out 1982–2007. Cause categories are only recorded for some accidents, and early findings can change.
