I've updated the plugin with a fix to the text bolding - it should work across all countries so let me know if there is an instance where it is broken.
Thanks for the link nAhu, I've found the issue with broken tagging on non-english languages. Whether this is new I don't know, but the metadata fields at the bottom of the page are being translated into the page language, which breaks the text matching that I use. Fixing this isn't hard, but would be a laborious process of going to each language, finding the text, and adding a mapping in the plugin. Not hard, but time consuming and I don't have much time for the next few months at least. Anyone is welcome to raise a PR if they want to do this though
