Several possibilities, if you mean in different missions check to see if you have the box for "no map contact update" in the gameplay options unchecked. If you mean disappearing contacts sometimes there, sometimes not, that could be a number of things including waves washing over the periscope head. For high seas I usually click on the depth gauge to order it up a couple feet, IE periscope depth is 60 feet and the waves are so high I can't see more than half the time, bring her up to 58 feet. Or even 55, depends how high the waves are.
