Bugs in content types

I am running the lastest version of Mac OS Sierra and the lastest versions of Chrome and Safari. Content created on Wordpress. On both Mac and LG smartphone ( latest Chrome browser )  the Dialogue Card forward progress button does not work. When pressed the button blinks and also appears to the right of the card count, but program does not progress to the next card. Any suggestions? (https://avatutor.com/annie-quiz-one)

Can someone please tell me why my audio files are being played in my interactive presentation I created? I appreciate the help.
