How can I prevent the mini-buffer from displaying previous commands in Emacs?

I am not even sure this is a previous command or a non-finished command or whatever, but I do know I really don't like it.

My problem is that some commands (or messages, or whatever) get stuck in the mini-buffer so that when I type a new command it appears there really quickly, and then the mini-buffer is back to the stubborn command. Some commands seem to be chosen, and after using lots of commands something else gets stuck there, but there is always something being shown that I don't want to see. I tried typing C-g lots of times to see if it would quit, but that does not work.

This is a picture of what I have now:

It does not matter what I do, that bit

Label: hl-line

will not leave. It does leave momentarily when a new command is typed, but it goes back. I don't like it, it is confusing, and I would much rather see there the last used command.

I did check the customisation options for the mini-buffer (the bottom part of it can be seen in my picture), but I found nothing that seemed to be what I was looking for.

Any ideas?

The mini-buffer has lost focus. Try C-x o (Control+x o) to regain focus. To cancel the command press C-g when you have focus in the mini-buffer.
