Beacons working?

[TurtleBurn]

I've made it to all 4 islands and unlocked beacons but, in the overworld, all the buff options on the beacon are grayed out. (yes I made it correctly, the beam shoots up) In the Nether I can select buffs but haste and strength buffs arent actually applied even if I can see the buff in my inventory. I don't know how to fix this or if its just a bug but id like some help :)
