Those symbols represent the companies that were in the Nasdaq 100 at some point in time, but were removed from the index. It's a dynamic index, and when you backtest using it (and the other WealthData indices) you get a true to life result because it correctly applies the stocks that were in and out of the index at the point in times of your simulated buys.
