Hi Don,
for the correct relief the straight edge should not rock. It should sit flat at the ends with a small gap in the middle frets.
So keep adjusting the truss rod.
This site has a good way to do it:

You may need to re level the frets with a straight neck.
Lets hope this helps. If not, you may need to sand the lower section of the neck cavity a smidge!
