randomly sorted category terms, plus changes one term to another

I reported for 5.x-1.1 that Taxonomy Super Select listed category terms Z->A rather than A-Z. And that it changed selected terms, so that selecting 140 resulted in saving 137, and similar. These problems all disappeared when I uninstalled the module.

Now I'm trying 5.x-1.5-1. Instead of sorting Z->A, it now seems to sort randomly, or maybe not sort at all. With a long list of terms in two levels, this is very difficult to use. But the show-stopper remains -- when I select, for example, "Health" (term ID 164), Taxonomy Super Select actually assigned "Technology" (term ID 144). This is the same problem in version 1.1. Again, uninstalling this module clears up the problem, though then have to fix the bad categories in whatever nodes Taxonomy Super Select messed up.
