I will use Wynn as an example. If you click on his defenses they show the correct level, but the incorrect damage. Look at the level 3 bunker. It shows it only does 4 damage. If this is intentional, it is just odd because it gives you some correct and some utterly false information.
I'm noticing this too. Various stats being incorrect for many buildings. Also noticed a Gold Mine in Wynn's base that was showing damage instead of production rate. (Halloween update on iPhone 6, iOS 8.1)
Well that's just weird...Maybe Wynn has gold mines that attack as well? That must have cost a lot of gems
