Retarget Manager not saving transformation changes

Hi , Please Answer this!!
I have followed this tutorial : Kubold To Mixamo Retarget Manager

When i click view pose to change the t-pose of my mixamo character and change it it doesn’t save i mean when i click hide pose then click view pose it’s the first pose so there arn’t any changes to it. How can i make it right?
