Your username: LordeJerry. In which minigame/server does the bug occur: Factions. Detailed description of bug: The tab names are all messed up. I don't know if its meant to be like this but it doesn't look correct. Spoiler: Image
Maybe the name aren't meant to be so long but the tags like "Nook" is for the faction's name. That's meant to be there also the colors are for different relation for example Purple -> Ally Light pink -> Truce Red -> Enemy
It's working as intended. You can try changing your client GUI scale settings or increasing the resolution of your Minecraft window to see if it will make the names fit properly like on my screen:
