For missing names you must create two new entries in "text":
agent_string_faction_overrides_name_override_championrom_kushm insert your name
agent_string_faction_overrides_description_override_championrom_kushm insert your description
You need the "agent_string_faction_overrides" table for the right unit card for your hero.
If you don't add it, you got a afroarabian hero unitcard, if i remember correctly.
Generally "agent_string_faction_overrides" table make excemptions for the appearance of some agent types for some factions, which differ strong from the normal appearance of the agents of their cultural or subcultural group.
