My /heads isn't working

[Salty_Carp101]

I have over a stack of Blaze heads but whenever I try to redeem them in /heads it says I need 10 more, even though I only needed 10 blaze heads for 1 mobcoin. I need help please

Hey,
It isn't a bug . You must right click all your heads to register them into /heads and then you can redeem them for mob coins.To register all heads in one time then press shift and right click them .

Thank You .
