Hostile Mobs on Teams Attack Other Player Teammates

[FrostyFiend16]

So I am developing a zombies game-mode where if you die, you get infected and become a part of the zombie team. On paper it should work and testing in survival servers show that zombies won't attack players on the same team, (note: friendly fire is false for both scenarios) but as soon as I hop onto the server where I am hosting the game, me and other players will get attacked and damaged by zombies. All the zombies are on a team called "infected" and friendly fire is off, and players join that same team. Am I doing something wrong, is it the server or does Minehut just not support that kind of thing?

Minehut servers uses something called paper and I think I've seen someone say you can't add mobs to teams on paper servers.
