I want to switch to right click but, there is no option to do that in the User Preferences. I should be located at the top of the Keymap section.
You appear to have been using an older version of 2.8 with a custom keymap prior. Even through reinstalled, the custom keymap was kept.
The way hopefully not to get the Preferences Panel at the top of the Keymaps is to switch to a default keymap like Blender which strangely also has a few of the changed keys which were in the custom keymap.very strange
