audio import issue

In Captivate 2019, I have a slide that has four buttons.  Each button when I click on it I can go to options.  In advanced options I have upload the new audio.  Clicked update actions and close action.  It will not play the new MP3 file. What am I missing?????

buttons and group

In a work captivate 2019 file we have a slide that when you run it has three slides contained into it.   They are all called slide 11. By clicking the button you will get the new image and text.  How do I get to see the layers or groups in this slide?  I need to change information in the chemical hazard portion of the slide.
