Catalina 3 volumes instead of 2?

I have 3 mount points and 3 harddrives displayed on the desktop.

The /Volumes/Macintosh HD - Data mount point seems wrong but am too afraid to remove the volume.

The old Macintosh HD was split into two by Catalina. Your personal data is on the Macintosh HD Data with full access. The overriding Macintosh HD is read only and contains the operating system for added security

You'll have to export photos from photos library, preferably in their edited form, whilst still in Catalina and import them back into Mojave library. Similar but not so drastic for Music library
