Thanks for the hints Ihor !

I still see the problem with org version 9.6.6 and your latest example
code. 

I also checked with emacs -Q which has org version 9.6.1.

I’m testing this on the attached file.

I also see that if I set the export scope to "subtree" instead of
"buffer" the process runs as expected.

Cheers,
Victor
