Two disks are displayed in mac os, what should I do?

Question

macOS

I reinstalled mac OS a long time ago, because of this, a second disk appeared in the "Storage" section. He stupidly copies the main disk, how and why he appeared - I don’t understand at all. It doesn't seem to bother me, but it does get on my nerves. What could be causing this problem, and how can it be fixed?

It's not a problem. Apple separated system data and user data in this way. Learn more https://support.apple.com/en-us/HT210650
