There seem to be cases where version 3.0 doesn't run an initial script that adds some data columns to the menu databases. There is an easy fix if you are having a problem.
Simply Deactivate and then reactivate the plugin.
NOTE: ONLY DEACTIVATE the plugin. DO NOT DELETE the plugin, as this will delete your menu data along with all of the plugin files. Deactivating/reactivating the plugin keeps all of the menu data and files in place, and forces a set-up script to run that failed to run when upgrading.
Sorry for the inconvenience. I'll have a new version out asap to address this problem.
