This may well correct the issue. However it seems like a lot of work to solve
an issue in which a single PST file is being shown twice in the Navigation
Pane. Surely there must be a route to de-select one of the instances?

Creating a new mail profile doesn't automatically create a new PST, although
it appears you believe it does. There will be no "new" and "old" PSTs for
the OP to copy between. There will be just the original PST which they can
use in the new profile.
