Yeah thats normal.
The right side should be scroll-able, it allows one to scroll down and select from the original non mod traits.
All the original traits are set to zero cost so they don't monkey with my costs and they are only provided because excluding them entirely creates issues any time someone uses a non mod based race and wants to keep some of their stats intact.
Yes it does mean you can add any of the original traits in at no cost but my job isnt to hold peoples hands and prevent cheating, folks are welcome to do so to their hearts content, as it is modding the GalCiv3GlobalDefs.xml is simple as pie so if folks want to give themselves unlimited points who am I to gainsay them. People can play however they like I just provide my mods to give them a broader scope with which to do so.
In fact if there is any desire for it I could include an optional edited defs file in the next release that would do just that.
Let me know your opinions below.
