You are confusing AWL and Bayes.  The autolearn thresholds apply to the
Bayes DB.  IIRC, Bayes scores do not contribute to the AWL.

A negative AWL score simply means that previous emails by this sender
had a lower score, so AWL generates a negative score to bring the
overall score closer to the previous average.  For a pure spam sender,
this effect should be minimal.

Other than disabling AWL, the only way to fix a score is to remove it
from the database.
