OneToOne related other model fields converted to boolean field check box in form to show or hide model fields doesn't work

You Saved me bro, i removed checked and it works fine What the Hell of this trivial messy bug that causing me circling

around for long time, it was really just checked and i added true and false cause i wasn’t convinced that

the check box has this property and remembered that it’s a Boolean field but forgot to remove checked

and try again
Thanks so so so much for you
