Broken audio player button

Hi, a page on my site has been broken for some time. It happened after a WP update. The music plays fine, but the timeline of the player extends too far to the right, and the speaker volume line is now below the speaker icon. I disabled all plugins except WPBakery which is needed for the site to display at all. A WP Forum suggested the theme may be incompatible with the current WP version. I would be very grateful for your help.

The page is JeffMarshMusic.com/music

I’ll attach a screen shot of the anomaly.

Thanks!
