Please explain your issue. How do you trigger it?
I'm trying to use the healthbar system through DeluxeCombat to show the health of a player below the playername, I contacted the Dev for DeluxeCombat and he checked everything and told me that it should be working, he said that it might be a problem with NTE clashing with DeluxeCombat.

Are there any errors in the console? Please use: https://pastebin.com
No there's not.
