Admin interface link on listinfo page

I installed MM 2.1b5 and copied the data files for a few
test lists to the 'lists' dirctory. I then ran update -f to
update the data files to the new version.

When I go to the list info page for one of the lists, the
link to the administrative interface is still pointing to the
original (production) web interface link.

Example:

Production version of MM's web interface:
http://lists.midrange.com/cgi-bin/listinfo/testlist

Beta version of MM's web interface:
http://lists.midrange.com/mailman2/listinfo/testlist

However, on this listinfo page, the admin link points to
http://lists.midrange.com/cgi-bin/admin/testlist

I have changed the DEFAULT_URL_PATTERN to
be 'http://%s/mailman2/', so I would expect the links to
have the correct url.

Additionally, when I go directly to the test list admin
page
(http://lists.midrange.com/mailman2/admin/testlist), all
the links on this page also point to old cgi-bin url.
