On further investigation, it looks like your database config is a little messed up.
The databases you are auto importing to don't seem to match the databases being used by the HUD.
Check that you have the correct databases configured for auto import (Tutorial: Using Auto Import) and for use in the HUD (Tutorial: Configuring HUD Options), and that you have run housekeeping (particuarly cache update) on all databases being used by the HUD.
