Access Control (tac_lite) tab's Scheme 2,3 values not selected properly

I think this is part of what contributed to my earlier issue at http://drupal.org/node/462254 (and the fact that I realized I also had to click 'Save configuration' on the Access control by taxonomy 'Settings' page to rebuild permissions), or at least compounded confusion.

When I edit the update/delete values (schemes 2 and 3), while they seem to apply properly, the page is refreshed with Scheme 1's select list options still highlighted. The settings appear to work as they should, it's just that the wrong values get selected.

For instance,

Scheme 1 (read):
vocabularytitle:
-none-
foo <-- SELECTED
bar <-- SELECTED
baz <-- SELECTED

Even if I choose for Scheme 2, the page refreshes with the same 3 options selected as in Scheme 1 above.

Scheme 2 (update):
vocabularytitle:
-none-
foo <-- SELECTED
bar <-- SELECTED
baz <-- SELECTED

When it should look like:

Scheme 2 (update):
vocabularytitle:
-none- <-- SELECTED
foo
bar
baz

If the text example above doesn't make sense, I've attached a screenshot that should help.
