Expected behavior

I've tried two methods to change item's custom model data and both of them didn't work.
First one is: minecraft:player_head[minecraft:custom_model_data={floats:[1]}]
Last one is: PLAYER_HEAD:CMD-1
And I'm only getting this problem in player_heads for now, the other items work well.
