ABM will only show you providers that your receiver has been told it can receive. Regarding the aerial, surely you know what wires are hooked up to the back of your receiver. Unless you invite us round for a cuppa, only you know what is there.
So first of all, which types of dishes do you . Motorised, multi LNB etc
Edit:
Aso, there are several Terrestrail/Aerial providers. You have to select the ones that apply to you. Selecting the Portugese, Dutch or Irish one is no use to people in England.
Looking at your old posts, you have moved over from ATV. Their tuner configs foe hybrid tuner has a quirky method. Lots of people do not disable the mode that they are no using, so they would see providers that they really cannot use.
Edit2:
To get ABM past the Freeview failure, disable the Freeview provider in ABM.
