Hello Lloyd,
Thank you for your question and I am happy to assist you with this.
As I can see the woff2 file is being served from the CDN.
You can try adding the *.woff;*.woff2
in Perfomance>CDN>Files types to import and also try using a custom files list and add the path of the files for example:
/wp-content/themes/some_theme/fonts/some_fond.woff
Make sure to save all settings and purge the cache once done.
You can also exclude specific font from the CDN, by adding it to Rejected files: list as mentioned above.
I hope this helps!
