Search checboxes don't work?

We just upgraded this weekend, and I notice that the check boxes in the search don’t show correctly. And it’s not that the data is there, and just don’t show correctly, I should be able to sort if that were the case.

Has anyone else seen this? Fixed it? It’s not a huge deal, but it’s annoying.

Those looking undefined. Not checked or unchecked?

Is the data accurate for that condition?

a boolean can’t be undefined. They should all be checked except of one checkbox.
