Hey AvengerBak,
Like other captains have said, you must hit all the ships in the cap to reset the cap. IF there is a ship unspotted, that ship will keep all of its "cap points". A good example of this is when you are trying to cap in a larger ship i.e. BB and a dd is with you. Like the example used above, the enemy team can keep resetting your points but that DD is getting "cap points" without being reset.
How far away from the cap were you? Were you shooting at the cap from a distance and only shooting the ship you could see? Especially with a ship that has the ability to hit multiple ships at range, keep resetting all the targets that you can see as you move closer. Remember once an allied ship gets on the cap, the progress will stop until that ship is sunk or leaves the cap again.
