Contact warning

[peabody]

I created two warships coming out of a harbor. When they come out, I don't get any "Contact Warship, Bearing........" They come out and come straight at me, I am testing, first time using the editor. A couple of minutes after them two merchants come out and I get contact info on them and they are twice as far away. When I click "Report contacts" I get "No sound contacts". But if I go above periscope depth I will get a "Ship spotted", I don't even have to be surfaced. Why do I get contacts on ship generated by the game but not on the ones I created?

One more question: (sick of me yet?) If I make a "group" to form a Task Force, will the destroyers leave the group to search for the sub like they do in the game?
