Try this: go to $AMBERHOME/test/rdc, and edit the "Run.dip" file
to add this line:

 &wt type='REST', istep1=0, istep2=15000, value1=0.0, value2=1.0, /

right before the type='END'

Then run the "Run.dip" script. The weight changes will be modified from
the original. Change "value1" above to 1.0, and see the change.

Check the "WEIGHT CHANGE" section of your output files: make sure there is a
line with REST. See if you can find some sort of difference between this test
case and your example.
