The non-English trick does work.

The problem is specifically with the English language. The Hero Build Creator works normally for other Languages that I have tried such as French. I checked the Chrome console, and when French was the language, there were no errors, however when English was the language, the following two errors were in the console.

Uncaught TypeError: Cannot read property 'abilitydata' of null edit?fileid=44233319819723434:200
Uncaught TypeError: Cannot read property 'itemdata' of undefined tooltips.js?v=_XPp8a0TuHXb&l=english:281
