Closed captions not displaying in interactive video

I created an interactive video with a Vimeo video in my H5P hosted account. Closed captions have been uploaded directly to Vimeo and I confirmed that they display when viewing the video on Vimeo. H5P doesnt seem to pull in Vimeo CC so I uploaded the .vtt file to H5P. I am able to see the 'CC' button but the closed captions do not display.

I've provided my H5P file and my .vtt file (changed to a .txt for upload here). Any help would be much appreciated.

Same problem but only in mobile view/app.

A mi me aparece lo mismo en el PC
