The problem is that in some countries we need to fix the location of borders and coastal area lines.
Following this post, we'll fix all of India's coast line in Waze's maps, going through the entire coast line might take some time though..
We seem to have issues with the fix for coastal areas and water bodies in the World server.
A new fix will be uploaded again to the server in a matter of a week or so.
