Preferences error with Big Sur 11.0.1

I just upgraded my macbook air to Big Sur 11.0.1 The new OS does not recognize the new System Preferences App from January 1, 2020 and proceeds to launch the old version from June, 2018 when I launch it from the menu bar apple or from Launch Pad. Both reference the old version from Catalina.

To get the current (Big Sur version) System Preferences to function, I have to first launch Finder, click on Applications, scroll down to the System Preferences App (from Jan 2020) and launch it then.

How do I get the normal process to launch the right version of this APP????

It appears that the 2018 Catalina version of the System Preferences App is located in a Carbon Copy folder, while the new 2020 version is located in the Applications folder. Unfortunately, I do not know how to force the normal opening of the latest Big Sur version of System Preferences from the menu bar apple.

Will that require a fix from Apple in ver. 11.0.2 ?

I have the same problem with preferences and looked in the Applicaions folder and found 2 versions. The January version works but The February version doesn't. Weird.
