I cannot reproduce it. Anyway, see my comments below.

It's out of exporter's scope. When you ask to export some buffer, what
is really parsed is a copy of the current buffer with
`org-export-blocks-preprocess' applied to it.

So, simply apply that function in your test buffer, and you will see
what is sent to the parser. That will explain why the results appear
twice.

In other words, tweaking the output of `org-export-blocks-preprocess'
will automatically change the outcome of the export process.
