Hi,
The problem is the graphics override file. I have not updated EDDS to use that, as it works fine without. But as long as you use it it will override any changes EDDS makes. The solution is to delete (or rename if you wan't to keep it) GraphicsConfigurationOverride.xml so that ED doesn't use it. ED will just recreate an empty GraphicsConfigurationOverride.xml, so no harm done.
On a side note, I should probably get around to make EDDS use GraphicsConfigurationOverride.xml instead, so we don't run into these sort of problems
