That sounds like you had BBF set to engage other settings. If you are in one shot (not servo), no tracking and no eye detect, and using single spot (either small or big), the focus will stay inside that spot. I've just tried it with mine, and I can't induce it to focus on anything outside of the spot. If you're in one of the zone modes, you will see the multiple focus squares inside that zone (it has to pick something to focus on inside the zone), but nothing outside the zone. You should check your custom settings to see what you had the BBF button set to. This isn't a problem with the camera, but with your settings. Or, it might be that you have a faulty camera, but what you are describing doesn't happen with a non-broken R7, unless you had programmed the back button to use other settings. If that's the case, it doesn't matter that you turned off the other settings.

I can't find a way of covering something I want to shoot and it permanently staying there.

What I have done is program my AF-ON button to use the "register/recall" settings, and set it to single spot (small) with no eye AF and no subject tracking. That forces the camera to focus just on what's under that spot (I can use it with one-shot or servo). It stays there. It works perfectly. I don't use it often, because I find the subject and eye-detect and tracking of the R7 to be superb. But occasionally I need to force the camera to focus on a particular thing, and that's a quick and easy way to do it.

What is going on?

It really sounds like a problem with your settings. You might want to reset everything and start over.

Alistair - big thank you. I discovered I had somehow set bbf to eye detect which would presumably be responsible for almost all of the above problems and some others as well. It seems ok now with a quick test. I was toggling eye detect on and off with the M-fn button when tracking but would the bbf button always overrride this when I pressed it o focus when it was set as above. It appears so.
Thanks again, I will get there.
