Audio button missing on card

Hi guys,

Please help, I’m desperate after trying this for an hour.

The audio button is missing on the new items.csv file downloaded from LLN. I was comparing to the old files (downloaded back in Jan) and this part of the code is missing

<audio style="display: none;" id="dc-audio"><source src="1612011340114.mp3" type="audio/mpeg"></audio><div class="dc-play" preload="auto"><svg class="dc-play-svg" version="1.1" xmlns="" viewBox="0 0 512 512"><path fill="#fff" d="M96 64l320 192-320 192z"></path></svg>

Does anyone facing the same issue or this is a known issue? Thanks for helping me!
