You might notice that the parameters fp1 through fp4 are missing from the wiki code, but a value still show up in each field in the table ("?"). Some parameters have default values when they're missing from the wiki code.
The following comprehensive list of parameters all have the default value "?".

str1 - str12

dex1 - dex12

con1 - con12

int1 - int12

wis1 - wis12

cha1 - cha12

bw1 - bw12

dc1 - dc12

fp1 - fp12

If you want any of the above fields to be blank instead of having the default value. leave the parameter, but don't put anything after the equal sign.
Example
bw1=1d6 |dc1=
The above will yield the following in the "Wyrmling"/"Breath Weapon (DC)" table cell.
