Describe the bug
It seems the "target format" dropdown has been tailored to match the Plex style theme and does not look good with the original Calibre-web theme.

To Reproduce
Steps to reproduce the behavior:

1. Go to CWA settings and scroll down.

Expected behavior
I would expect it to have a white or light background so it is more easily readable on the native theme.
