Hi Eric, and thanks a lot for the feedback.

By 'fix', I of course meant 'fix my own mistake'...

I forgive myself here, though, because I have been using LaTeX for
many years without having to pay any attention to this kind of chunks,
which are (for me) inserted automatically.

But it is certainly not obvious to me why the content of this chunk
takes precedence over the file extension -- after all, the manual
says: "Files with the ‘.org’ extension use Org mode by default."

I can certainly understand if the content cannot be examined after
each insertion, but, as there are many things in Org which are done on
the fly, I felt compelled to ask.

(One could also imagine that Org would detect upon loading the file
that there is a conflict between the modes -- but I also understand
if this is not something reasonable to ask.)

Regards,
a.
