Requesting help with how to get the new NR dashboard working

Found the issue already. Remember your thread from June about FontAwesome and Material Design and a different syntax? Material design icons vs font awesome
Spoiler alert: there was not really a different syntax, just syntax errors in writing those and understanding why it happened that way. You're making the same syntax error again. Please go back to that thread and see if you understand what you did wrong. It's the exact same issue now. If you can explain to me what happened back then that caused the error, you should be able to see what went wrong now.
