The dynasties do have proper names in Ck3. I've included the zip of the entire converter, which I think the mod is inside (called Imperator_start) and the save itself. Thank you for taking the time to look into this, I had thought maybe this was a common issue with a known fix but I guess not.Nothing wrong in the log. Do those dynasties have proper names in CK3? Upload your ck3 save and the conversion mod (zip both mod file and the mod's folder) and I can investigate.
