Help with Zenburn Theme

Hello, this is my first post here. I really need help customizing the “Zenburn” theme. It has a white box that highlights the entire document. I would like to disable this white box and have the entire document be the same color as the background (dark grey). I tried fiddling with the style settings but I didn’t find anything.

I want the entire document to be the same color as the line in the carret.

Any help?

Themes is something that doesn’t really work well in Npp, since, at first,
it was only designed to “theme” the document, and later it was,
more or less, adapted to the rest of the ui.
Glitches like the one you mentioned are therefore unfortunately part of the problem.
