Adding Units to a Faction

I just tried adding some Greek Hoplites to Macedonian Faction, using export_descr_unit and export_descr_buildings. Worked fine, units appear as trainable, but in the review panel they appear as Peasants with Hoplite description.

Does anyone know how I make the proper Hoplite icon appear in review panel?

There I helped someone add axemen to the gauls faction (with correct unit cards and info images). It should be able to help you. If not, just add a reply, and I will see what I can do to help. Good luck.
