[Bug] Radio button appears unset by default, but has still a default state

[feikedonia]

Settings -> Imput Devices -> Touchpad -> Click Behavior,
and (...) -> Scrolling:

Click Behavior
the Secondary click with two fingers and middle-click with three fingers option is physically set as the default. But the radio box doesn't show it.

Scrolling
Scroll with two fingers is the default, but isn't shown graphically.

To discover this bug, I had to test it out, so Click Behavior has now a ticked radio button. It was in the same state as the Scrolling-section.
