Highlighted background row seems to spill over

[zyrre]

Whenever a row is highlighted it seems that all following rows receive the HighlightedBackground color? To illustrate, here I have row 5 highlighted:

There is no difference among modules, all that have row highlighting act the same.

Any idea what can cause this?

For info: I just cloned the repo and built it, ran bin/wtfutil. Also, adding something like colors: background: red to the config will change the background color, but adding this: colors: highlight: fore: red back: red does not change any of the colors.
