It's a dynamic campaign, so ships and convoys all over the world are moving all the time. Just because a contact was revealed to be in one spot doesn't mean it will stay there and wait for you to sink it

If you're talking about nearby map contacts, then is the same - a contact is solid colour only when you have direct visual on it, and as soon as you lose sight of it, it starts "aging" and getting lighter. Get closer or make periscope observations to update it.
