Never attempt to re-parallax any range finding scope below 10 yards or you will lose the longer distances.
This is what you are currently experiencing.
If you need to range find closer than 10 yards buy a close focus adaptor.
Ps, a 40x will always range find better than a 35x.
I know, I've had a 35x, a few 40x and a couple of 45x which were even better.
