Character do the animation in retarget animation window but not in the main view port

I imported a human model and then right click on another human model that has animation then I choose “retarget animation” the retarget opened with this model as source so I added the skeletal mesh of the new model as target and double clicked on the animation sequence

I can see the new model do the exact animation of the source model then I exported the animation and selected that animation and put it into the main view port and pressed play but I can not see the new model doing the animation. Why the new model did not play the animation inside the main viewport ?

Here is the retarget window and the new model in the right is playing the animation normally

I dont know why the model did not played the animation but when I tried again it worked
