Stretched audio exports with new duration but original audio speed, resulting in cropped clip

Hello, I am very new to audition. I am trying to work on some video game sound effects, and timing these effects properly with the animations in my game. I am trying to use the stretch function to shorten a clip from .75 seconds to .6. It sounds fine in the editor, but when it is exported the ouput is .6 seconds of the audio running at its original speed, which cuts the last portion off and doesn't work for me. Is there any way to make the stretch function actually work on an exportable file? Thank you very much for any help, it is so frustrating to try to do something so simple for so long with no luck!
