WordPress audio

Hi
I used to use media elemnts for single player audio files on my site here

https://www.robfostermusic.co.uk

The latest posts on the front page was added using add media on the posts page and selecting audio, when the page first loads I see the grey audio player with the airplay symbol on it , which is what I want, but when it finishes loading it loads a black player, which looks like the media elements player, which is what I used to use and I don’t want anymore, I’ve deleted the media elements plugin, but ithe black player still shows, so can anyone tell me how to get the grey player to show all the time?

thanks

Rob
