in the default installation, you're able to set the 6 extra fields, in all situations... but if you select the category to be a type Personal, even if you create a extra 4 or extra 5, there are already some hardcoded details in the template itself, instead of being already set.. but they are not active when you first choose that Type...
and also, the text they are supposed to contain are not present in the lang file... take a look:
Code:
Content visible to verified customers only.
as you see, the extra 3 is set to a default empty... extra 4 is having content... phrases are absent, and there is no way to know this detail in the actual install... maybe you need to activate these defaults, as they are needed but not complete...
