wp manager

hi,
i think your plugin is really useful.
but there are some problems…

I could import categories for posts
but i use wp manger and it has a
custom post-type. this post-type
(called job_listing) correctly appears
at the gui.

but when i import categories
(‘succesfully’)
i see no categories added.
(i did not even uses slug)

are they recoverable?
will they haunt my database?
is there any sql that will
sort this out?
