Correct. If you use a jailbroken phone to buy Gems, you need to make sure you are purchasing them via the actual store. Sending in invalid purchase receipts will cause this data error. To fix this issue, uninstall and reinstall the game as you did is the correct solution. While reinstalling the game usually should not erase game progress, it's advised for players using iOS 7 or higher to write down their 6 letter/digit friend code and other game statics (name, level, stage unlocked, coin/gem balance) just in case the uninstall unlinks the account from the device.
