Yet, despite various issues over many decades, the airline has zero fatal events where a fatal event is defined as a death of a passenger or crew member as a result of some sort of accident.
In any case, in terms of actual outcomes, Southwest has had a pretty good track record over the lifetime of their airline.

However, they may not have updated their site beyond the incident summary because Southwest is still listed as an airline with zero passenger fatalities.
The Southwest page does mention the 2018 incident and fatality, and was updated the day of the incident in fact. However, the incident isn't "numbered" as a fatal event--instead it has a UL bullet instead of an OL number, which looks like a mistake.
On one hand, AFAIK the event wasn't SW's fault at all--they'd performed maintenance on the engine to standards. The fan blades failed due to a material fatigue issue, and happened to hit the engine cowl at its weakest spot and detached it.
But I thought Airsafe still would've counted that as related to the operation of the plane, though, and the FLE for that flight would be like 0.007 (1/143) and still round up to 0.01. Since only flights with a fatality at all count for their calculation that'd be an overall FLE of the same.
