I have seen this many times, I go to design a ship and it show a lower (older) shield than is actually used. In this case I want to consider a design change for a battleship. It has class III shields, but a check of an existing BB has class iv. Here is a save to see it, if you have not already seen it.
Correct, it's not updating to the latest Class IV shields but keeping Class III. We'll fix that, thanks!
