Some monsters are both "normal" monsters (with XP, skillups, awakenings, plusses) and materials. For example, the Mech Dragons).

When PADListener filters the monster list to remove the materials, it does not filter the monsters, and the monster remaining might be lower level fodder ones instead of the better one.
