I should reckon you need a grammar as well, and a test example.
I've checked the current version into the logon tree.
If you parse, e.g. "sun kamashi" and regenerate, you should see:
sún káámàà shí
but you get
"sun kama shí"
instead. Open the generator tree and display the fs for the top most V
node. Scroll down to the top-level attribute SUPRA.
On the TONE diff-list there are a few reentrancies with the FIRST values
further down the list, but no concrete values.
Interactively unify in the type constraint supra_reent, and you will see
that all elements on SUPRA.TONE now have a definite value (high or low).
The type essentially closes the open list (by unification with a ghost
list under LEN) and instantiates the tones back to front.
Hope this helps hunting down the problem.
