No advanced options to change audio box properties' appearance

I've been trying to select an image in my pdf file and add an audio clip when it is clicked. However after going into 'edit' mode, going to 'sound',  selecting the region over the image, it creates an audio playback box with a white background and black border with a play button at the lower left corner, masking over the image it's intended for. When importing a mp3 file, I select the 'show advanced options' checkbox but there are no options to change this. The documentation shows there are many more options but I don't see it. I'm using Acrobat Pro in Adobe CC. I have the newest version (25.1.20937.0) I think. BTW, my pdf file was created by saving an MSWord file to pdf. Not sure if that affects anything.
And lastly, when playing the audio file, there are no options for the play index to automatically return to the beginning. You have to manually scrub it back.
