resolution problem and how can I solve it ?

how can I loud my resolution ? I had my apply and save resolution but when i want to load it . I can’t , I don’t know why it loads LastUserConfirmedDesiredScreenWidth and LastUserConfirmedDesiredScreenHeight not my LastUserConfirmedResolutionSizeX and LastUserConfirmedResolutionSizeY . I know the resolution I’m loading is for stand alone but should’t my load resolution be last user Confirmed Resolution ?
