This is all backwards. The real question is why GNUmed
apparently does not replace the placeholder as intended. If
that happened as intended LaTeX would never see the %.

Of course - you told GNUmed (or Python, rather) to not
consider the % as a substitution prefix (by escaping) and
LaTeX to properly understand the % as % (by escaping). Hence
you end up with proper renderings of the placeholder format
in the LaTeX source file and thus in the PDF: GNUmed does
not touch what it sees as literal values and LaTeX
understands "\%" to be processed as "%".

As I said. One would want template, instance, and log.
