How to stop buzz tv open up on default categories

I have a buzz box x5 and I'm putting it together as I want it. The remote is controlling the on/off on the tv as well as the remote which is what I want. I've hidden the categories I don't want to see in the list provided by my provider as I've created a favourite list but here's the problem, when I turn on the tv/box with the remote it opens up on live tv as specified but automatically default to Peacock tv which is what I don't want besides I've turn it off (hidden) not to see it I want it to default to favorite instead. I've looked everywhere and I mean everywhere how do I remove Peacock tv or get the box to open up on favorites by default?

I moved your post to proper place for help

was peacock the last channel you watched before shutting down?

I don't remember but does it open up on the last channel by default? I just don't want Peacock at all
I've got it on Me tv right now I will shut it down and turn it back on and see if it will fix it but I don't think
I had it on Peacock because I took the whole morning building up favorites to have all the channels I watch
on favorites and Peacock is certainly not there

Ok I think I got it you might be right I'm still learning this thing it's not the firestick

It goes to the last channel you were watching

Nope guys when I turn it off at night with the remote and it also shuts off the tv, in the morning again it opens up on Peacock by default still even if I turned it off on say Cozi tv in the morning again over and over every morning when I turn it on tv comes one as well as the box and when I click on Live tv it goes to f.... Peacock tv. Since it's an android opened up not a shut tight firestick, is there anyway I can go in the software and remove Peacock tv since I don't watch that
