loadposition does not work in the description of categories and brands

loadposition does not work in the description of categories and brands

I tried to put the {loadposition location name}
but it does not work as if the plugin was not interpreted because in the front end I remain the {loadposition position name}

As a custom html form I also activated: Interprets plugin code

where am I wrong?
