What’s the bit at the top of the left-hand panel?

I’m working on my first landing page using this plugin, so the chances of me missing something obvious are high…

What is the non-scrollable segment at the top of the left-hand column about? I’ve marked it in the screenshot below. I can’t see any way to alter it, so I’m wondering whether it’s been put there by some other plugin…. I’d actually prefer it wasn’t there at all (unless it has some use that I haven’t stumbled across yet….)
