How to change track highlighting?

Somehow I’ve changed the way track highlighting works in Audacity 2.3.2 on Windows 7. Previously when I highlighted a section, the highlight would change the color behind the track data. Now the track data color remains constant and only the sections above and below the highlighted area change color, like this:

Changing the theme doesn’t make a difference.
Thanks in advance.

Accidentally clicked on multi-tool ? …

Yes, that was it! I figured it was something easy, but I was trying to look for something in Preferences. Thanks!
