UI on Dark Mode unusable

Trying to return to OmniOutliner after few years break (admittedly, I dropped OO out of my toolbox because very poor Ui experience). Returning, I was hoping that worst bugs would be fixed by now. Well, I’m using Dark Mode on my Mac and …

I’m just wondering how the styles sidebar checkboxes can be totally unusable in dark mode. The tick on checkbox is invisible. Dark grey on dark grey gradient? What? Why?

And of course, there is no way to override Dark Mode on OO (Or is it? Where?)
