The admin UI looks up available apps like this::

  zope.component.getAllUtilitiesRegisteredFor(
            grok.interfaces.IApplication)

Therefore only application types are found, that are registered in the
'local' registry, which in fact is silently assumed to be the global one
(and it should be in the regular 'zopectl' case).

When you say, that there are different storages, that might mean
different registries had to be looked up.

As Martijn said, please create a bug report on launchpad with a
setting/problemdescription, explicit configuration file contents etc.,
so that we can all reproduce the problem and make sure, we all talk
about the same stuff.
