Essentials Vanish broken (cant unvanish and particles show)

if i do /v i just get invisibility for an infinite time, thats literally all

if i /v to go back, the invisiblity stays ._.

also everyone can see my particles... even without the essentials.vanish.effect permissions

for any other permissions, players dont have a single permission close to vanish. they just have build, /spawn and /help ETC
