Use unset(... CACHE) to remove a variable from the cache.
set() and unset() without "CACHE" work on the normal variables, which are like a layer of variables on top of the cache variables.

Unset ( variable CACHE )
works. The documentation for unset() looks adequate also.
I would like to mark this bug as resolved but see no option to in Mantis.

I can do it, maybe you don't have permissions to do it as reporter.

So, marked as resolved with no change required, as requested.
