Invisibility potion - says "-100% Waypoint Transmit Range"

This is a small thing, not sure if easily fixable, but making note of this If you hover over an Invis potion, it says "-100% Waypoint Transmit Range". This indicates that players that drink this potion can't be seen on the player locator bar. Given that the player locator bar is disabled, there's no reason for it to say this. See screenshot
