I asked you to share a demo of the error. You did not do so, therefore I did not help.
What has led you to the conclusion that it did work for the Japanese version but doesn't for the English version? Did you have it working in the Japanese version, set it up the same way in the English version, then seen it not work? Or are you assuming that something about the translation messed it up solely because you have the English version and it does not appear to be working?
I ask because I have not noticed any differences in the English translation, and I don't see what would cause the error from a brief scan of the Steal script. My inclination is to think that the script is not setup correctly, which is why I asked for a demo with the error and not just the blank scripts.
I am not ruling out that it could be an error with the script, but if it is a user error then I would need to abstractly consider every possible thing in the script or configuration that could cause your error, and I would prefer to be able to see the demo as then I could tell you what is causing the error. Plus, it takes a lot less time on my end if you share the demo. So, please, share a demo or blank project with the error recreated and I will take a look. Otherwise, I will not.
