Please explain your issue. How do you trigger it?
For example, I have a staff group. It shows STAFF in front of the players that are staff. However, the prefixes disappear after about 1 - 5 minutes. Then I have to do /nte reload in order to bring the prefixes back.

Are there any errors in the console? Please use: https://pastebin.com
There is nothing that appears in console.
