plugin code appearing above player gallery

Hello! I’m having an issue with the player gallery where it’s displaying this code above the player images (gallery number is different depending on the list, but all lists are affected) and then displays the players in one column below that:

#sp-player-gallery-492 { margin: auto; } #sp-player-gallery-492 .gallery-item { float: left; margin-top: 10px; text-align: center; width: 33%; } #sp-player-gallery-492 img { border: 2px solid #cfcfcf; } #sp-player-gallery-492 .gallery-caption { margin-left: 0; } /* see gallery_shortcode() in wp-includes/media.php */

I found gallery_shortcode() in wp-includes/media.php but I don’t know enough about php to see if there’s anything wrong in there, but I’ll post what appears to be the relevant code below.

Another admin on the site was adding some new players over the weekend and said it looked fine before she did that.

It happens with the short code as well as just selecting the player list in the Team page settings. If I switch it to the List view, it looks like it should, so it’s only the gallery view.

The theme and all plugins are up to date. Changing the theme and deactivating all the other plugins doesn’t fix it. I’ve also checked my media and gallery settings and tried changing some things, but nothing is fixing it.

Let me know if there’s any other info I can give you to help track down the issue! Thanks!

media.php code:

add_shortcode( 'gallery', 'gallery_shortcode' );
