As Leo said, it enables flatview. If you want you can disable that in the settings or setup your flatview columns as Leo described.
@Leo 's solution solved the problem.Sorry i was not clear with my earlier post.I had to ask as after lot of tries i was not able to figure out but felt awkward when solution was so simple n easy.It's been almost 3-4yrs i haven't configured much of DO but now after upgrading i'm trying to learn again.
