Loads correctly but after refresh doens't anymore

[Japhys]

Whenever I save the page and have a look it works correctly, however with the next page load it reverts to standard footnotes. Uppercase numbers, text at the end of the page

After refresh the bigfoot js is gone from the page source. When I disable Auto-add in plugin config and add js in twig, the js doens't disappear but bignote popup still doesn't work
