your density and volume plots look the same.
you should not see volume changes with ntb=1. it's impossible to tell
if the problem is in your plots, your data extraction from the mdout,
or sander. maybe you could copy and paste the relevant output directly
from sander? paste in the average and rms sections from the end of the
run. also tell us exactly how you got these values for plotting.
