Directory plugin - cant select categories

Have a feeling that this might be a small error somewhere, but not sure what.

I have the directory plugin setup on a new standard WP install, nothing other than the directory plugin so definitely no conflict with any other plugins.

If I add a new listing from admin access, it all works fine. I tested a purchased listing though which cant select any of the categories that have been created.

I simply copied all the taxonomies to create my categories.

Is this a known error or did I miss a step on the setup?

Thanks.
