Resouce points does not add up correctly in driver career

I chose increased resource points for driver and reduced resource points for ai, since i don’t want to complete or simulate practice sessions. However, as the season progressed, i realized that i’m not getting enough rp. When i observed, i saw that the indicated weekly resource points does not add up as it should’ve been. 
Look at the screenshots: at first, i have 127 points. I should get 180 weekly points which would make it 307, but i end up with 277 at the end.
