BaseCamp "sidebar" - low contrast

I am using BaseCamp (latest version - 4.8.4) on a MacBook Pro (latest OS 10.14.5) and the sidebar where one selects data (folders, routes, waypoints, etc.) has pretty low contrast ... medium gray text on a light gray background (see attached screenshot). I cannot find any settings within BaseCamp or my Mac that will allow me to better see the folder/data lists. I've tried both "Dark Mode" and "Light Mode", and the contrast remains terrible. Any ideas?
