Please explain your issue. How do you trigger it?
I created some ranks and implemented them into the groups. The ranks will be displayed great as prefixes, but when I add them to the tablist they disappear after 60 seconds. But only for my alt account, not my main account.
The alt account does not have op, my main has.

Here is my config.yml: https://pastebin.com/JHXuCB9H
Here is my groups.yml: https://pastebin.com/RCfyAHkc
