Restarting SE did not help. I tried renaming my v19 and removing the v20 config directory with beta two, and loaded with default config. The only change I made to the configuration was change the color scheme to black and select the All symbols - Dark background symbol color scheme. Open a project, wait for the tagging to finish restart and still nothing.
The main color scheme comes through fine but no symbol color scheme settings are applied. Even in the sample code window within the options area.
