There was a glitch with storing prefs in an earlier 7.x version, and apparently it ate the prefs for the color set options. I'm going to put in a fix that patches in the original values if the current settings are empty (which is causing this issue).
For now though, if you just open the prefs file and find the lines near the top that look like this (only without values) and paste these lines in their place, the problem should be fixed.

Those lines need to be un-wrapped to work.
