Issue with Audio Files in Adobe Portfolio

Hello. I am using Adobe Portfolio as my business website, since it is included in my yearly CC subscription. (I use Adobe CC for business, as well.) My business is voiceover, so I have many .mp3 files uploaded onto my website. My problem is that for some reason each audio file has a spinning circle behind it, as if it is trying to load (see image below). This is quite distracting, but goes away once you hit the play button and the audio file starts playing.

My website has been up for almost a year now, and this issue is still present. Although the audio files play just fine, I feel as though my website would look much better and more professional if my audio files did not have that spinning circle behind them to begin with. Does anyone know if there is a way to fix this, or if I can change how my audio file sound bars look on my website?

Thank you in advance!
