Why an entity was discarded - The Why Discarded function
After choosing several states, entities which do not match the current
selection are moved to the Entities
Discarded window. To determine why an entity was discarded, select
it from the Entities Discarded window then select Why
Discarded from the Entities
menu or click on the Why Discarded
button
on the toolbar.

If an entity is discarded that you believe should still be present, the Why Discarded function allows you to quickly compare your selections with the features present for the entity in the key.
