I think I figured it out now
If the same thing happens to you,it seems that after all its not any issue.You just have to follow couple of steps. first go to 3D settings,then adjust image settings with preview and click on use the advanced 3D image settings and then apply to save.And now you are free to play with the 3D setting and after saving them it wont reset.like in my case...so basically my conclusion is,that if you jump between the 3 settings, Let the 3D aplication decide/Use the advanced 3D image settings/Use my preference emphasizing: to quickly do some settings and previously not apply one of those 3 basic categories of settings,your settings will reset...Well may be its bit silly,but we could call it a small glitch,cos as a ATI Catalyst user I've never had to worry about such a thing.As soon as I did a change in settings,they changed and remained as Custom settings no matter If I did them in one of the Preset setting...
