Duplicate "iCloud Drive (Archive)" folders

I have two iCloud Drive folders.

Is this normal behaviour?
Can I delete one (how about both)?

Running macOS Mojave 10.14

Neither of these are your actual iCloud Drive folders where your iCloud Drive data is stored.
If you don't need their contents, you can delete both of them.

iCloud Drive data is stored in ~/Library/Mobile Documents

If you don’t have that folder, then it means your machine isn’t hosting a cached copy of iCloud data locally.

When turning iCloud Drive off, files that were contained in iCloud Drive are saved to a newly created folder called "iCloud Drive (Archive)" (if the option to save files is selected when turning iCloud Drive off).

Turning iCloud Drive on and off again will create additional folders, such as "iCloud Drive (Archive) - 1", and so on.
