I had the same problem but fixed it. Its not perfect but atleast its working.

• Open APE, create a new GDT and give it any name.
• Create a new Asset in the created GDT.
• Name it something like "mp_ssi_fixed".
• Set the type to "ssi".
• Make sure the new asset is created in the correct GDT.
• Change the settings to this: http://i.imgur.com/8xVHEtc.jpg
• Save everything and open your map in the radiant.
• Select your sun volume (make sure nothing else is selected).
• Open the entity info and change the light state 1 to "mp_ssi_fixed".
• Press F8 and rebuild the lighting.
• Have fun with the new light!

If you dont like the sun position, change the values (Pitch/Yaw).
Make sure that ALL settings are the same, only pitch/yaw can be changed without getting into lighting problems again.
Its a beta and we just have to wait for treyarch to fix that stupid lighting but.
