Quicklaunch on App World wrong version

I'm currently on version 18 for quicklaunch and I want to get to the new version 20. App world says it is on version 20 and I went to download it. When I check the version under the quicklauch option menu it shows that I am now on ver 17. I found that some of the features on 18 were now gone. On my options ---> application it says it is ver 20.

What's going on? I got it back up to 18 by using the update button, but I can't seem to get it to 20. I have tried fully deleting the application and re downloading.
