Re-hiding "More Properties" in the Contextual Bar

So, while idly clicking around the interface, I saw there was a little drop-down option on the contextual bar, with one option that said "More properties", so of course I clicked it. A couple extra icons appeared, that's fine, I guess, but I can't figure out how to re-hide them! I know it's just a couple icons, but for some reason, it's really bothering me. I don't really want to wipe my configuration or anything, is there an option to shrink it back?
