How does this happen and what the heck does it really mean?

Southwest Airlines abruptly grounded 66
Boeing 737 aircraft in its fleet last Wednesday after issues with the carrier’s aircraft weight records were discovered.
In an internal memo to employees on the matter that was obtained by the Chicago Business Journal, Southwest said: “Today (Wednesday) we discovered the weights being sent to our Dispatch Operation did not match our other weight records for a number of aircraft in the fleet. As a result, and out of an abundance of caution, we have stopped flying those aircraft to recalculate the weights of the aircraft in question and reset the program.”
Aircraft weight is important because dispatch personnel and pilots need the correct information to determine the amount of fuel to load and other data needed to safely operate a flight."
