/fog remove fog_hell doesnt work

i was showing my friend how the /fog command worked and i decided to use minecraft:fog_hell, when i tried to remove it, the game told me the fog id doesnt exist/ is invalid, i even added the id thing at the end and it didnt work

 

i used /fog @a push minecraft:fog_hell h to add the fog,

/fog @a remove minecraft:fog_hell to remove it

i also tried /fog @a remove minecraft:fog_hell h to remove it

it should have removed the fog, it said the id was invalid
