After a clean install of Catalina Disk Utility is showing 3 drives

[AddisonIII]

Has anyone else run into this issue where after installing Catalina, Disk Utility is new showing 3 Macintosh drives. 1st says Macintosh HD. Used 10.57GB. other is 11.16GB. 2nd entry is showing Macintosh HD-Data.Used 3.89GB. other 17.85GB. 3rd is Macintosh HD-Data. used 987KB. other 22.09GB.
You can sit and watch as these values change with nothing more than Disk Utility running. The 2nd entry is showing home and says it can't be removed. The 3rd when high lighted says it can be deleted.
Can anyone please tell me if I should delete the last one or if they all should be left alone? I have never seen anything other than 1 Macintosh HD entry until now.

i have Container Disk 1 / Macintosh HD and Macintosh HD - Data

I don't seem to have a recovery partition now.

I don't understand the new system. Does the new volume to install stuff is now Macintosh HD - Data ? because the Macintosh HD only took 10GB or so now.

Also, I lost about 35-40GB of space after the updateate to Catalina, normal ?

I'm wondering if recovery is located on HD-Data? I have been contemplating removing of the 2nd HD-Data listing, but hate like heck thinking of doing another install if that other is needed.
