Unable to remove or hide favourite

Hi, I am trying to remove/hide a favourite from the Home Screen on my Apple TV.
The guide tells me to locate the favourite under the settings in the library and long press on the desired favourite with the select button.
Then choose from the pop-up selections.

Nothing pops-up!

I am assuming the selection button is the big button on the Apple Remote.
I go down my list of favourites,selecting the one I want then press and hold the big button.

As I said nothing happens. A single click on the favourite will toggle the tick against it but long press nothing.

Has this broke in 773 or has the process changed?
