Does anyone understand this twodimes discrepency?

[Mizzles]

What am I missing here? Here are 2 similar hands plugged into twodimes with completely different results ??? In both cases person holding pocket pair has flopped open end straight vs. opponent flopping two pair. Why are the win/lose results not even close? Aren't the number of outs for the PP the same in both?
