Some new default player heads to using the wrong role skin.
Reproduce:
Zuri use the skin of Noor
/give @p player_head{SkullOwner:MHF_Zuri}Sunny use the skin of Ari
/give @p player_head{SkullOwner:MHF_Sunny}Noor use the skin of Efe
/give @p player_head{SkullOwner:MHF_Noor}Makena use the skin of Zuri
/give @p player_head{SkullOwner:MHF_Makena}Kai use the skin of Makena
/give @p player_head{SkullOwner:MHF_Kai}Ari use the skin of Makena
/give @p player_head{SkullOwner:MHF_Ari}
You mentioned "Sunny use the skin of Ari" twice.
At this point I wonder why they added those as MHF skins, rather than new head blocks.
