Doesn’t work on some pages

Great plugin thanks, but the most recent version doesn’t work on some of my site’s pages.

Works here: https://www.worldenergydata.org/world-fossil-fuel-production-and-primary-energy/

But not here: https://www.worldenergydata.org/the-energy-system-of-china/

Blowed if I can figure out why? Suspect I’m missing something obvious.
