Bilt-in player doesn’t appear

Hello,

I’ve encountered a problem with adding the WordPress built-in media player to a page on my website. While editing the post, it is well displayed, exactly as it should be, and in txt edition mode I see this code:

[playlist ids="25,26,27,28,29,30,31,32,33,34,59,71,79,81,82"]

but when I update the page and check how it displays, in the place where I should see the player, there is only an empty space. Can you please explain me why it happens and what I can do to fix it?

Thank you!
