Once you select your vampire type (base) there are set stat points that you can use. Once you distribute them go back to the base selection. Select the same base as before. Make sure that you dont click on another base (it resets the character's stats). When you go back to the stat distribution page your character has his stats that you've left.

On top of that you can add the ones that they give you for picking that base. Make sure that you don't fill all the stats as soon as possible. You won't be able to start the game if you have left over stats.
