Manohar,
Take a look at the forum post below. I've seen some very strange OTM UI issues that were resolved by following the steps listed. Also, if you have a chance to list the steps you took to reset the VPD objects in the OTM database, I'm sure it would benefit other forum users at some point.

Hope this helps!
