price reduction display bug in LoL Store

Hi Riot team, I think that I have discovered a bug in the LoL-store. The old price and the price reduction percentages of the Hextech bundles are displayed wrong. You see the red number which is crossed out? It shall show the old price of the items in the bundle. This is shown wrong in picture 2 and 3. Also the discount percentage of the third bundle is not correct. Thank you for listening and goodbye! :)
