Hi Sunil,
I was able to reproduce this on 0.7.2... but just once. It's strange. Only the first import didn't work. After I tried a second (third, and fourth) time, it worked fine. Make sure you close all browsers after import.
Please try it again and let me know if you still get the problem on 0.7.2 after performing the import more than once.
Thank you,
Eric
