Trouble making keypad/numberpad enter key behave like normal enter

I'm trying to map the enter key on the numberpad/keypad of my external keyboard to the normal enter key. Some programs like sublime send code and certain IDEs (like Spyder) treat the two enter keys as distinct. I was able to create the shortcut in BTT, but the change doesn't occur.

i.e. I've mapped "⌅" to ↵
