I used your reproducer (thanks for providing it!) and was able to
duplicate your results (more or less - I get this

   7c7b2c131fcf88c89639d10326a972f0ff25]:

before the second set of results).

If I evaluate both code blocks by hand in the org buffer and
*then* export, I don't get the extra junk.
