Hey, I've found an issue with BetterNameTags.
For some players the default Minecraft name tag is not hidden, and for others the Aristois name tag is not displayed at all.
I'm on the newest version of both Minecraft and Aristois (1.21.4)
I include two Scscreenshot to further clarify this behavior:

Notice: The players agree that their names can be seen publicly
