Nicobar islands territorial waters altered

As pointed out in an OSM note,

At a first look it seems to me that the entire territorial waters outline for the island group has been shifted to the south, and there might need to be a reversion somewhere. Can someone look into it please? (I don’t have access to the usual tools at the moment)

Yes, the car Nicobar Island has to be corrected. The Indian border should include this island.
Can someone, who knows about maritime borders, please make corrections.
