Discrepancy between cold wallet and CoinTracker

I had to manually tranfer coins from CoinTracker to a cold wallet. For example: now my cold wallet shows a balance of 10XYZ but CoinTracker shows only 5XYZ. It seems that in CoinTracker the manual transfers are not included in the total; however under the XYZ in CoinTracker shows the same number of transactions as in my cold wallet.
Any explanations?
