I took the screenshot about thirty minutes before I posted on the forum. I went to the CCleaner site and downloaded the update directly, so now if I "check for updates" it says "congratulations, you're using the latest version". Like I said in my post, this is the second time I noticed that the "latest" and "installed" versions were the same. Last time I checked was about a month ago when the update was from 5.75 to 5.76 and it did the same thing. It's not a big deal, since I just take it to mean there is a new version available, and whether I update through the app or download from the site I get the correct new version, but I just thought you might like to know that it wasn't showing the correct new version number.
