Upgrade screen for tower/ballista tower/castle/catapult is showing the old range

[This game is laggy]

For example, in the current version of the game, the ballista tower's range has been increased to 6, which is accurately shown in the Info screen.



but in the Upgrade screen, the old value which is 5 is still shown.



I see the same thing with catapults, towers, and castle as well.
