That's $USER..$ macros, and they're not exported in the UI for
security reasons (although some of them find their way there anyway
through plugin output).

First of all, you'd be better off not using environment macros at
all. When you do use them, Nagios has to calculate ALL macros
instead of just the ones you use, and some of many of them are
quite expensive.

Secondly, try replacing your script with something that echoes the
output of 'set' and 'env' to a tempfile and see what you get there.
It's possible the documentation regarding their names is wrong.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
