Very Interesting though, or should I say troubling

Very Interesting though, or should I say troubling, somehow the first level2 you show has a 9 dollar increase or 64.29 percent to $23.00, yet the second one has just a 4 dollar decrease or -28.57 percent to $10.00. Both have a date of 5/23/14, So exactly what is the price, and what was the price?? Strange wouldn't you think??
