Yes, I'm terribly disappointed...I was looking forward to creating a superrace maxed out in every category...I guess I'll just have to settle for the Thalans (next best thing). No bug here.
To the OP: This is normal behavior. When you make a custom race and assign all their points, then hit back, and select a canned race and hit "next", you are then in the customization screen for that canned race, with their points. They get points too, just not as many as a custom race. If you hit back again, and come back to that screen and see points there, its the same points as before...the "changes" to that race dont take effect until you hit "next" from that screen, and reset every time you hit "back".
Yes, adding those points to a canned race can allow for some very powerful combinations. The tradeoff for the custom race is that you get to pick "exactly" what you want with all the points. Whether or not this is actually balanced is the subject of discussion of a number of other threads on the subject, that I'm sure you can find with a little effort.
