Two Volumes Named "Macintosh HD - Data" Now Appear in Disk Utility in Addition to "Macintosh HD".

I am familiar with the creation of Macintosh HD - Data. Indeed, this volume, plus Macintosh HD appeared in my system after updating to Catalina.

In trying to fix generic icons that have now appeared in my Finder file system, I opened Disk Utility and found that I now have two Macintosh HD - Data volumes:

Is this supposed to happen?

Update:

Time Machine just presented this error message, which indicates that there should NOT be two Macintosh HD - Data volumes:

Each time you put a copy of Catalina on it installs another HD Data and may double your other data creating multiple Volumes with the container.

you must erase each HD Data drive in recovery (world spins) then erase the top layer (your physical drive). Then download Catalina in recovery NOT your copy. That is what is creating the multi volumes. Then set up your Mac from your time machine backup
