Row Rule affecting the wrong rows?

(classic UI, latest Kinetic Cloud release)

I have a wizard generated Row Rule that highlights the row red if a checkbox is true. But for some reason it is also highlighting one other column in the grid, like this:

Has anyone seen anything like this?

Edit: that checkbox is just CheckBox01 - there is nothing special about it, I’m just hiding the business use case name. I imagine there is something weird/special with that Complete column in this grid, but I doubt there is anything we can do about it.
