Audacity Window stuck to top of mac toolbar

Audacity’s toolbar disappeared and it’s now attached to the toobar at the top of the mac home screen. I have closed this window and opened new ones many times, quit and restarted Audacity, searched around settings, and it’s still stuck like this. Should I uninstall and reinstall?

No. Not yet. There’s a simple fix I need to look up.

There it is. Audacity > Window > Zoom.
