Lost default window snap areas

I have always used the default window snapping configuration. But it appears that I now have no snap areas defined and it's not falling back to a sensible default like it used to.

In the past when snapping hasn't worked, I have restarted BTT and that usually has resolved it.

Is this a bug? Do I now have to add my own snap areas instead of relying on defaults? Thank you in advance!

2019 16-inch MacBook Pro
macOS Monterey 12.4
BTT 3.821 (1964), latest from what I can tell (including alpha versions)

Ok weird, now it's working again and I don't have an explanation for why.
