I don't know why or how you get this, but this has nothing to do with
`org-src-preserve-indentation' since there in no global indentation in
your code (i.e., a line starts at column 0).

You can use C-u C-x = in order to know what it is.

What happens if you run (org-export-execute-babel-code) on your Org
