I completed every single last campaign on legendary by myself and all read completed on legendary, however none have registered as achievements, therefore I cannot unlock my prize helmet in Halo 5 Guardians. Please help 
Hey OP, looks like the Halo 4 level āComposerā hasnāt registered as being completed on Legendary. If you run through that again the achievement should pop and then you will be able to get the halo 5 rewards
