pyg, the way modding is done, modding commands overwrite unit attributes. If a unit already has an attribute, a mod will update that attribute. If you have a unit with 10% regen and set it to 20% regen in a mod, then it will have 20% regen, and not two attributes with 10% and 20% regen which would result in 30% regen. You are overwriting the "pretender for nation" attribute three times, so only the last one will stick. If you want the units as pretenders for multiple nations, then you need to make copies of them.
