Mac Sierra says "installed" but version 10.9.5 showing

I am trying to upgrade MacBook Air (2013). When I go to the App store to download Mac Sierra, the download button is not available, as it reads 'Installed'. However, when I go to 'About This Mac' it shows I am running version 10.9.5. I have restarted my laptop a few times. I am trying to upgrade to run other apps that require a more current version of iOS. Any help you can provide is greatly appreciated!

Listen... I have been at this computer all day and night. Starting at 10:30a on 1/16/2018. If you see the downloaded or installed on Sierra in the App Store WITH A GRAY TAB YOU CAN NOT CLICK. It is because you have DOWNLOADED AND INSTALLED.


OPEN APPLICATION. CLICK ON LAUNCH PAD. YOUR INSTALL SCREEN OF SIERRA WILL POP UP AFTER.


I SPENT HOURS WITH TECH SUPPORT TO FIGURE OUT THIS PROBLEM AND THEY HAD NO CLUE EITHER. WE RESET USING COMMAND SHIFT AND OPTION, REBOOTS.


I GOOGLED FURTHER AND MY RESULTS WERE RIGHT HERE. I AM A PERSON OF CONSISTENCY SO I WASN'T GIVING UP AND GLAD I DIDN'T. HOPE THIS HELPS OTHERS!
