All of those things are appropriate to send through the support form!

If you included an email, you should have heard something back about the tag-related one by now, though, even if it was just acknowledging they got it.

But I'm not seeing any aliasing on that tag at all, so I don't think it's a wrangling issue - which means something extra weird is going on with it, because it sure does look like there's works there that don't belong, unless the wrangling was just recently fixed and the indexing hasn't caught up.
