It looks like you are looking at an older version. If you are seeing Process Versions 2003/2010/2013 you do not have Lightroom Classic CC open.
Go to Help>System Info... and verify your Lightroom Version. If it doesn't say Lightroom Classic Version: 7.x [######] you have opened an older copy of Lightroom installed on your computer. Close this copy of Lightroom and make sure you open Classic.
