Missing module warnings with advanced_help

When enabling the advanced_help module I immediately started seeing warnings on the admin pages and in drush:

The following from drush but the same wording appears in the admin pages.

The following module is missing from the file system: <em class="placeholder">multipurpose</em>. For information about how to   [warning]
fix this, see <a href="https://www.drupal.org/node/2487215">the documentation page</a>. bootstrap.inc:1128
The following module is missing from the file system: <em class="placeholder">stark</em>. For information about how to fix this,[warning]
see <a href="https://www.drupal.org/node/2487215">the documentation page</a>. bootstrap.inc:1128

Multipurpose was the default theme at the time that I enabled advanced_help. Changing the default to bartik did not help. Stark was not installed but I did download and install it but the warnings continue.

When advanced_help is disabled the warnings cease.
