I am creating a custom taxonomy for the first time. I am trying to add a Location taxonomy. What I am actually trying to do is use existing categories to make them into locations.
I went into the database table wp_term_taxonomy and manually changed the taxonomy column of the ones I wanted from category to location.
This seemed to work pretty well, posts are assigned to the desired locations and everything seems to be fine, until I go to the Locations page in the admin interface and find myself with an empty list, even though it detects the existing locations and lists them:

If I manually add a new Location through the interface it appears on the list correctly.
What could be causing this?
Categorynot being changed into aLocation. Now I know: if the parent term is missing, the child term will not be shown on the list. (I wonder if this whole question should be deleted or would it be of any use to other people?)
