This feature was last tested 3 months ago. I don't really remember how it works, but the DB records are messed up on staging so..
Also, I'm not really sure why the title has been changed by bot.
You are the first one other than me to submit code via this feature. I appreciate it, as for right now CodeRush only has one file per language. I will look into what happened.

Oh, ok

Also, I'm pretty sure the title was changed because I submitted something else under a different name. It just overwrote the original.
However, my original one was a mistake 😂 so I guess it was lucky?
